Adds the cc_fuzz target via a cc_fuzz module. Also implements the
libclang runtime interface for the x86 toolchain to allow host-built
fuzzers.

Test: Build a fuzzer (with all topic patches), notice that you now
have a host-built fuzzer :)

Looks like the reason for it existing has been fixed. It should probably
just be removed.

These VNDK libraries did not have both core and vendor variants built
for the cuttlefish target when I initially build the list, and thus
they were missed. Add them back.

Test: Build walleye with no-vendor-variant VNDK enabled.

So that projects can override the flag through cflag (CPPFlags are
appended after CFlags).

When no-vendor-variant VNDK is enabled, the vendor variant of VNDK
libraries are not installed. Since not all VNDK libraries will be
ready for this, we keep a list of library names in cc/vndk.go to
indicate which libraries must have their vendor variants always
installed regardless of whether no-vendor-variant VNDK is enabled.
Also add --remove-build-id option to the strip script to facilitate
the check of functional identity of the two variants.
Bug: 119423884
Test: Add a dummy VNDK library and build with
TARGET_VNDK_USE_CORE_VARIANT := true, with the corresponding
build/make change.

Emit address-significance table which allows linker to perform safe ICF.
Clang does not emit the table by default on Android since NDK still uses
GNU binutils.
With the flag, binary size is decreased. For Marlin:
