How it works:
1. build/make/core/Makefile generates a txt file with the kernel
version, which is taken from an explicit BOARD_KERNEL_VERSION value,
or extracted from the kernel image on the source tree, or extracted
from the kernel image extracted from the prebuilt boot.img.
The file is saved at
$ANDROID_PRODUCT_OUT/obj/PACKAGING/check_vintf_all_intermediates/kernel_version.txt.
2. If PRODUCT_ENABLE_UFFD_GC is "default", meaning the GC type needs to
be determined by the kernel version, build/make/core/Makefile copies
kernel_version.txt to
out/soong/dexpreopt/kernel_version_for_uffd_gc.txt.
3. build/soong/dexpreopt/config.go writes the the UFFD GC flag to
out/soong/dexpreopt/uffd_gc_flag.txt. The flag is determined by an
explicit PRODUCT_ENABLE_UFFD_GC value or by contruct_uffd_gc_flag.py,
which reads kernel_version_for_uffd_gc.txt and determines the flag
accordingly.
4. dex2oat takes the UFFD GC flag from uffd_gc_flag.txt.
5. post_process_props.py mangles ro.dalvik.vm.enable_uffd_gc based on
the same logic.

(This was missed in aosp/2876756, which copied only the bcp jars)
This hardcoded location is used by dex2oat to compile the dexpreopt
artifacts. The copy rules are currently generated by java_(sdk)_library
for source builds, and their prebuilt counterparts in prebuilt builds.
After this change, the copy rule will be bifurcated between source and
prebuilt builds
1. For source builds, it will come from java_(sdk)_library
2. For prebuilt builds, it will come from the top-level prebuilt apex.
Since there can be multiple prebuilt apexes in trunk stable,
HideFromMake will be used to determine which deapexed jar to copy.
The bifurfaction is expected to be temporary. It is needed for now since
the `apex_contributions` which will be used for source vs prebuilt
selection have not been populated completely.

Starting from aosp/2594905, dexpreopt depends on
`$PRODUCT_OUT/product_packages.txt`. When PRODUCT_PACKAGES changes,
dexpreopt has to rerun for all apps. This is not ideal.
After this change, dexpreopt uses a per-app product_packages.txt that is
filtered by the app's dependencies, and it uses `rsync --checksum` to
prevent the file's mtime from being changed if the contents don't change.
This avoids unnecessary dexpreopt reruns.

Before this change, dexpreopt was often broken with optional libraries.
This was because the CLC construction was done in Soong at an early
stage, where we don't have sufficient information to determine whether
an optional library is installed or not.
For example, the "Settings" package uses an optional library called
"androidx.window.extensions". On some devices, the library is installed,
but on some other devices, it's not. Soong always adds the library to
the CLC, meaning the CLC is wrong for devices which don't have the
library. This change fixes the problem. See the tests below.
After this change, the CLC construction is done by a Python script
invoked at a very late stage. It uses product_packages.txt, which is
generated by Make, to determine whether an optional library is
installed or not, and filter out libraries that are not installed.
Note that optional libraries are still added as dependencies by Soong.
This is because dependencies have to be added at an early stage. This
means what dex2oat eventually uses will be a subset of the dependencies,
which is fine.

The motivation is to reduce file size and in-process memory footprint
for "services" (which is currently the only system server jar that has a
profile). For other system server jars that have no profile keep using
"speed", as enabling "speed-profile" for them would completely disable
AOT-compiled code.

dexpreopt.GetGlobalConfig uses a OncePer to only parse the config once.
If the config contains missing paths, which can happen in partial
manifest branches, the missing path errors will only be reported on
the first caller to GetGlobalConfig. Fix the nondeterminism by
wrapping the PathContext and capturing any path errors and reporting
them to all callers to GetGlobalConfig.

This reverts commit 0b1c70efbc.
The reverted commit was based on the idea that uses-libraries that are
explicitly specified in build files should not be implicitly added to
the manifest, as that would mean that anything added to the build files
will flow to the manifest.
Although this logic is correct, it prevents propagation of
uses-libraries from dependencies, which is wrong: if a library has an
explicit uses-library property in Android.bp, this property is expected
to be propagated to the library's dependencies. Failing to do so would
mean that every user of that library has to add uses-library property to
their build files, which doesn't scale (see b/214255490 for example).

A number of tests in the cts/tests/signature/api-check check for the
accessibility of classes from the android.test.base,
android.test.runner and android.test.mock libraries. Some tests expect
to find the classes other do not. Unfortunately, the tests use
libraries, specifically compatibility-device-util-axt, that depend on
the android.test... libraries which causes Soong to implicitly add
<uses-library> entries to the manifest so that they will be accessible
at runtime. That causes the tests that do not expect to find the
classes to fail.

This CL updates platform_systemserverclasspath,
systemserverclasspath_fragment, and
prebuilt_systemserverclasspath_fragment to write entries for
STANDALONE_SYSTEMSERVER_JARS to systemserverclasspath.pb. A new property
`standalone_contents` is aded to `systemserverclasspath_fragment` and
`prebuilt_systemserverclasspath_fragment` to list the standalone system
server jars in the APEX, and entries will be written to
systemserverclasspath.pb accordingly at build time.
To add more context, these entries will be consumed by derive_classpath
in order to generate an environment variable
PRODUCT_STANDALONE_SYSTEM_SERVER_JARS. The environment variable will
then be comsumed by odrefresh to determine what jars to preopt on early
boot.
Note that the variable should not end with "CLASSPATH" because the list
is not used by runtime as a classpath. It is just a colon-separated list
of jars. System server loads the jars separately with paths hardcoded in
the code.

This is necessary in order to expose the copy rule to Ninja. Otherwise
Ninja has a build rule that depends on the copied jar (namely, dexpreopt
commands for all subsequent system server jars that have the current one
in class loader context), but no rule that creates it, so Ninja fails
with a "no rule to make ..." error.
The change only affects system server ed in Android.mk
Previously the problem existed, but was hidden by the fact that the only
system server jar defined in Android.mk was the last one on the list, so
no other jar depended on it. Now that updatable apex jars are also
dexpreopted (https://r.android.com/1828115) the problem was uncovered.
