Add bionic mount points under /bionic
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
Test: m blueline, cf_x86, aosp_arm
The aforementioned files and symlinks are found
