Use file_contexts for flattened apexes
Because flattened apexes are installed in /<partition>/apex, associated
file_contexts file should be modified to accommodate path changes and
also merged into target-wide file_contexts.bin file.
Soong now emits modified file_contexts via LOCAL_FILE_CONTEXTS, and
these files are collected into a temporary file_contexts.modules.tmp
file, which is used as an additional input of file_contexts.bin.
Bug: 166518492
Test: m file_contexts.bin
check the contents of file_contexts.concat.tmp file
