Scudo is a hardened usermode allocator that is part of LLVM's compiler-rt
project (home of the Sanitizers). clang allows for -fsanitize=scudo as a
possible command line option to link the shared Scudo library to a binary.
This patch add Scudo as a potential sanitize option. Scudo is not compatible
with ASan and TSan and will be disabled if either is enabled.

Test: aosp compiled with m -j
Test: local experiment with scudo: true to ensure that a test target
(tombstoned) could be linked with scudo.

To save space in the recovery partition, modules installed to the
partition are restricted to be built in the first architecure (i.e.,
32bit for 32bit-only device or when TARGET_PREFER_32_BIT is true, and
64bit otherwise).
Most notably, this change removes the 32-bit variant of the linker
(about 1MB). The linker was installed regardless of whether there is a
32-bit executable or not. Now, the unnecessary linker is not installed
and it is guaranteed that all modules in the partition are built with the
same architecture.

Test: m -j
Test: out/target/product/<name>/recovery/root/system/bin/ has only one
variant of the linker.

VNDK-Ext are modules with `vndk.enabled: true` but not having
`vendor_available: true`. In addition, VNDK-Ext should be checked by
source ABI checker. This change fixes the regression introduced in

Recovery variant of a module is now by default built with
-D__ANDROID_RECOVERY__, thus eliminating the need to define a custom
macro to conditionally compile the module for the recovery mode.
(Of course, they can define their own macro if needed)

Recovery partition has same layout as system. In other words,
executables are installed to <recovery_root>/system/bin and libs are
installed to ../system/lib.
This is made possible because the recovery partition is now
self-contained, i.e., shell, adbd, etc. are hosted in the recovery
partition and thus we no longer has to mount the real system.img
to /system. So /system is now available to executables built for
recovery mode.
Bug: 63673171
Test: `adb reboot recovery; adb devices` shows the device ID
Test: Select 'mount /system' in the recovery mode, then `adb shell`.
$ lsof -p `pidof adbd` shows that libm.so, libc.so, etc. are loaded from
the /lib directory.

For a vndk_prebuilt module that was built with 32 bit binder, add
"binder32bit: true" to its Android.bp module.
This will add .binder32 suffix to the name.

* Pass LLVM_{OBJCOPY,STRIP} to makefile rules.
* strip.sh is used only in soong-only mode.
It will use llvm-strip and and llvm-objcopy
when --use-llvm-strip is given.
Keep flags of strip.sh in alphabetic order.
* Tested build/soong/scripts/build-ndk-prebuilts.sh
by adding "UseClangLld": true, to soong.variables file.

Modules may have multiple variants for each architecture, and
SOONG_GEN_CMAKEFILES=1 was generating CMakeLists.txt for all of
them, overwriting the first normal variant with the last (and
likely least normal) variant.
Keep a map of generated CMakeLists.txt files, and only generate
each one once.

Every time the toolchain adds a new warning, we had to suppress the
warning in every external projects that violates it, or disable it
globally -- which we end up doing most of the time since the first
option is way too time consuming.
Add a separate cflags option for external projects and move existing
-Wno-* flags there so that we can enforce better code quality for
internal projects.
TODO: Move more -Wno-* flags to ClangExtraExternalCflags
