Create input symbol files to generate GKI modules header
under include/config. By placing files in this generated
directory, the default filters that ignore certain files
will work without any special handling required, and they
will also be available to inspect after the build to inspect
for the debugging purposes.
abi_gki_protected_exports: Input for gki_module_protected_exports.h
From :- ${objtree}/abi_gki_protected_exports
To :- include/config/abi_gki_protected_exports
all_kmi_symbols: Input for gki_module_unprotected.h
- Rename to abi_gki_kmi_symbols
From :- all_kmi_symbols
To :- include/config/abi_gki_kmi_symbols
Bug: 286529877
Test: TH
Test: Manual verification of the generated files
