Enable HWASan for multiple modules in one place(Soong)
Environment variables HWASAN_INCLUDE_PATHS and
PRODUCT_HWASAN_INCLUDE_PATHS can be used to enable HWASan for multiple
modules, by just adding the module directory to the env variable.
Bug: b/271948407
Test: Set specific module directory to above env variable and check the
assembly codes of output elf files after building, finding hwasan
related symbols inside.
