Previously, this was restricted to targets that enable R8 full mode, but
that was really just a temporary carveout to avoid disrupting other
targets. Since then, R8 full mode has been enabled by default for all
app targets, and the hash-based mapping mechanism is further integrated
into various debugging and retracing pipelines.
As of now, there are are only a very small number of targets that have
enabled optimization/obfuscation and are still using R8 compat mode, so
the build-time impact of this change should be minimal, and there should
be no functional runtime side effects.

When targetSdk is >= 30, the system verifies that you use a valid
signature V2+ certificate. Uncompressing ndk/dex files or aligning
the zip file will break a signature V2, so these apks should really
just set preprocessed: true.

This provides significant size savings over the default compatibility

min_sdk_version signifies device version and does not need an sdkKind to
describe it fully. Update the type and cleanup existing usages. As a
side benefit, we also get better error handling since users can no

followup CL

The -libraryjars argument to r8 was missing transitive dependencies, and
so complained when there were classes used in the program JAR which were
not provided via libraries. This CL propagates transitive dependencies
to the r8 command to reduce the warnings that are generated for missing classes.

`min_sdk_version` is used to represent the api_level of the device and
its type will eventually become android.ApiLevel. OTOH,
`sdk_version` property represents the API surface a module builds against
_and_ the version of that API surface. For
R8/D8, the additional `--android-platform-build` should be determined
using the sdk_version of the soong module and not min_sdk_version, since
min_sdk_version will not contain information about the api surface used
for compilation.
The unit test for `core_platform_app` in TestR8 were passing since
min_sdk_version was not set, and therefore it implicitly defaulted to
sdk_version.
Also created a custom struct to propagate params to the helper dex
functions

Provide the `--android-platform-build` flag to R8/D8 for targets that do
not specify a stable min SDK. This includes all targets that do not
specificy an SDK version (e.g., services.jar, SystemUI.apk) and all
targets that specify core_platform (e.g., framework.jar).
Follow-up work will expand the set of cases that qualify for this flag,
but for now this captures some of the highest priority targets.

This allows targets to opt-in to running R8 without the -ignorewarnings
flag. Ignored warnings can cause code to be optimized incorrectly, so
this makes the build safer for such targets.
Ideally ignore_warnings should default to false, but all targets need to
be fixed for that to happen. As a first step, provide a mechanism for
individual targets to ensure they do not introduce regressions.

Bug: 192032291
android_test defaults to using R8, but with shrinking, optimization and
obfuscation disabled, eliminating most of the benefits of R8. Instead,
use D8 by default, improving build performance and avoiding any other
issues that may arise in test-specific code related to whole-program R8
execution. An initial audit shows that android_test targets that *do*
enable shrinking or optimization also explicitly opt in to R8.
A follow-up CL will do the same for android_test_helper_app, but that
requires some additional auditing of downstream targets.

Standalone D8 invocations tend to be shorter-lived than R8 invocations
that involve deeper layers of bytecode optimization. Introduce a
separate set of JVM flags to pass to D8 invocations which limit the
runtime JIT tiering, reducing overall compile times and significantly
reducing total CPU consumption for D8 build workloads.
