Add prebuilt ABI checker support to soong

This commit adds prebuilt ABI checker support to soong so that
`cc_prebuilt_library_shared` and `cc_prebuilt_binary` are checked.

To opt out the check, add `check_elf_files: false` to your module.

Bug: 119086738
Test: lunch aosp_sailfish-userdebug && CHECK_ELF_FILES=true make check-elf-files
