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.

Setting use_rro_for_product will automatically generate an RRO package
which contains resources with 'product="{PRODUCT_CHARACTERISTICS}"'. The
RRO package will be installed to /product partition. The app will be
compiled with '--product default', making the app identical to all
targets.
Motivation for this change is to minimize divergence of system.img.

Test: boot and idmap2 dump

In the Bazel rule, the actual AndroidManifest.xml file isn't available
in the providers of the android_binary dependency. And for good reason,
we should also rely on aapt2 to dump the manifest contents from the
final packaged APK anyway, but this auto gen script doesn't support
reading the output of aapt2 dump.
This CL adds a simple reader of the output of `aapt2 dump xmltree`, and
enabled if the xmltree content is passed to this tool instead of
AndroidManifest.xml.
Also fixup auto_gen_test_config_test.py. The test was completely failing.

SymlinkTree is one of the action types Blaze returns in response to
`aquery` (action query). build-runfiles is a tool copied from Bazel
to implement this action (see src/main/tools/build-runfiles.cc in
the Bazel Git repo). It creates a symlink farm (i.e., a directory
hiearchy consisting of symlinks) from a given manifest. Mixed builds
need this tool the mixed builds (in particular, every Python applicaion
has a runtime symlink farm).

This CL adds a number of changes to make the assignment of system
properties to be less confusing.
1. Added `a ?= b` syntax, which is called optional prop assignments. The
prop `a` gets the value `b` only when there is no non-optional prop
assignment for `a` such as `a = c`. This is useful for props that
provide some reasonable default values as fallback.
2. With the introduction of the optional prop assignment syntax,
duplicated non-optional assignments is prohibited; e.g., the follwing
now triggers a build-time error:
a = b
a = c
, but the following doesn't:
a ?= b
a = c
Note that the textual order between the optional and non-optional
assignments doesn't matter. The non-optional assignment eclipses the
optional assignment even when the former appears 'before' the latter.
a = c
a ?= b
In the above, `a` gets the value `c`
When there are multiple optional assignments without a non-optional
assignments as shown below, the last one wins:
a ?= b
a ?= c
`a` becomes `c`. Specifically, the former assignment is commented out
and the latter is converted to a non-optional assignment.
3. post_process_props.py is modified so that when a prop assignment is
deleted, changed, or added, the changes are recorded as comments. This
is to aid debugging. Previously, it was often difficult to find out why
a certain sysprop assignment is missing or is added.
4. post_process_prop.py now has a unittest
