Kiyoung Kim 0d8908c2e4 Move sanitizer.libraries.txt logic into Soong
Currently sanitizer.libraries.txt module is defined from Makefile, while
all logics to create the list of modules is implmented within the Soong.
This change moves sanitizer.libraries.txt module definition into Soong,
so it can be generated without sharing list of modules over Make
variable.

Bug: 339131599
Test: AOSP CF build succeeded, with same list of modules in
/system/etc/sanitizer.libraries.txt
