Install vintf fragments and init.rc files in Soong

Determine the install location of vintf fragments and init.rc files
in Soong so that they are available to Soong-generated module-info.json
entries.  Collect the vintf fragment and init.rc files requested by all Soong
modules, deduplicate the list, and install them in Soong.
