Use file_contexts files for flattened APEXes
Previously, soong emitted APEX_FILE_CONTEXTS_INFOS make var which lists
"all" APEXes and file_contexts.bin used all of them regardless whether
an APEX is installed or not.
This doesn't work when there's a vendor specific APEX which uses vendor
specific labels. Other lunch target may fail to build due to "unknown
label" which is introduced by the vendor APEX which is fact not supposed
to be installed.
Now build/make/core/Makefile creates file_contexts.modules.tmp which is
a collection of file_contexts for flattend apexes which are to be
intalled.
Bug: 166518492
Test: m file_contexts.bin
check contents of file_contexts.concat.tmp
