Subject: [PATCH 1/3] [clang][InstallAPI] Add input file support to library
This patch adds support for expected InstallAPI inputs.
InstallAPI accepts a well defined filelist of headers and how those headers
represent a single library.
InstallAPI captures header files to determine linkable symbols
to then compare against what was compiled in a binary dylib and
generate TBD files.
