When pack_relocations is false and clang lld is used,
pass --pack-dyn-relocs=none to lld.
Bug: 80093890
Test: build and boot with USE_CLANG_LLD=true
Change-Id: I0ffe77a111d7fbab5afaa1395d09734a8a390e09
* USE_CLANG_LLD is unedefined in current builds.
* When USE_CLANG_LLD is defined to 'true' or '1',
use clang's lld instead of ld or ld.gold.
* When lld is enabled:
* ld-only flags are not passed to 'lld'.
* location_packer is disabled.
* Use new lld's --pack-dyn-relocs=android.
* When lld does not work:
* In Android.mk files use LOCAL_USE_CLANG_LLD := false.
* In Android.bp files use use_clang_lld: false.
* Only arm, arm64, x86, and x86_64_devices have LLD flags;
all other hosts and targets do not call lld yet.

This reverts commit fa00dfda13.
Reason for revert: New Build Breakages in git_pi-dev-plus-aosp-without-vendor/aosp_walleye-userdebug and git_pi-dev-plus-aosp/aosp_crosshatch-userdebug

Proposal for adding SHT_RELR sections in the generic-abi is at

Comparison with relocation_packer for aosp_marlin-userdebug:
$ du -B1 -s */out/target/product/marlin/system
996958208 base/out/target/product/marlin/system
1008340992 no_pack/out/target/product/marlin/system
997801984 sht_relr/out/target/product/marlin/system
base contains a build with current settings.
no_pack contains a build with relocation_packer disabled.
sht_relr contains a build with SHT_RELR sections enabled.
relocation_packer was saving 11,382,784 bytes (no_pack - base).
SHT_RELR sections are saving 10,539,008 bytes (no_pack - sht_relr).
Bug: None
Test: Built aosp_marlin-userdebug image, boots on device.

AConfig() now duplicates Config(). Replace the uses of AConfig()
with Config(). Leave AConfig() for now until code in other
projects is cleaned up.
Test: m checkbuild

Now that android.ModuleContext does not include blueprint.ModuleContext
we can rename android.ModuleContext.ModuleBuild to
android.ModuleContext.Build without colliding with
blueprint.ModuleContext.Build. Leave ModuleBuild as a wrapper around
Build for now to avoid having to update all the users outside
build/soong simultaneously.
Test: m checkbuild

Descriptions currently look like:
[ 0% 4/29328] cc out-soong/.intermediates/external/clang/lib/Sema/libclangSema/android_arm_armv7-a-neon_denver_static_core/obj/external/clang/lib/Sema/SemaCodeComplete.o
This is not very helpful - most of the characters are used to show the
output path, which contains useful information like target architecture,
but also contains most of the path to the source files twice, and less
useful information like the exact variant name used by soong.
Make the descriptions look like:
[ 0% 3/29329] //external/clang/lib/Sema:libclangSema clang++ SemaTemplateInstantiate.cpp
This is //path/to/module:modulename tool relative/path/to/source/file
Test: builds, looks pretty

This only applies to shared libraries on the device, and like stripping,
we'll let make do the actual packing if we're embedded in Make.
