This change adds following files and symlinks:
Files:
/bionic/lib[64]/lib{c|dl|m}.so
/bionic/bin/linker[64]
Symlinks:
/system/lib[64]/lib{c|dl|m}.so -> /bionic/lib[64]/lib{c|dl|m}.so
/system/bin/linker[64] -> /bionic/bin/linker[64]
/system/bin/linker_asan[64] -> /bionic/bin/linker[64]
The files serve as mount points for either the bootstrap Bionic or the
default Bionic from the runtime APEX. init does the bind-mounting during
booting.
The symlinks are there to not change the ordinary paths to the bionic
files; there are many places that the paths are implied or hard-coded,
e.g., dlopen("/system/lib/libc.so") or DT_INTERP pointing to
/system/bin/linker in the vendor prebuilts.
Bug: 120266448

It was discovered that we were building some objects inconsistently due
to an optimization in cc_library to only build objects once and use them
for both the static and shared libraries. But static libraries didn't
get system_shared_libs set automatically, and we didn't notice that we
would have built the objects differently.
So static libraries now get the default system_shared_libs, we allow
adjusting that for static vs shared in a cc_library, and we disable the
optimization if the linked libraries are configured differently between
static and shared in a single cc_library.
This triggers dependency cycles for static libraries that libc/libdl
use, so fix those cycles here.

When building with soong Android.mk files are ignored in directories
that have Android.bp files. Only parts of bionic have been converted to
Android.bp files, including some directories that have subdirectories
with Android.mk files.
Add Android.soong.mk files to include subdirectories to any directory
that has an Android.bp file but also has subdirectories with only
Android.mk files.

Building with USE_SOONG=true will build with an Android.bp file if it is
present in the directory, otherwise an Android.mk file. Only a few of
the bionic directories compile with soong, so include all of them from
the top level Android.mk file and remove the top level Android.bp file.
Individual subdirectories with Android.bp files will use soong with
USE_SOONG=true.
