We need symbol files for /bionic/* paths.
New property "mountsource" is added to specify the "real" module that
the bionic mountpoint module is a mountpoint for. The real module
provides path to the unstripped elf file, which is installed to the
symbols/bionic/* path.
Bug: 123985838
Test: m libc.mountpoint libm.mountpoint libdl.mountpoint
linker.mountpoint
$(OUT)/symbols/bionic/bin/linker, bionic/lib[64]/lib{c|dl|m}.so exist

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.

Test: m blueline, cf_x86, aosp_arm
The aforementioned files and symlinks are found
