Support for incremetal platform prebuilt APIs

Browse Source 
This change provides support for prebuilt incremental platform API (i.e.
API changes associated with a QPR, as opposed to a major dessert
releas).

This feature is provided via the existing prebuilt_apis module with the
introduction of a new attribute:

    allow_incremental_platform_api

While typical platform prebuilt APIs are presumed to be under a
directory structure that follows the pattern:

<version>/<scope>/<module>.jar
<version>/<scope>/api/<module>.txt

Where <version> is limited to a single integer signifying the API level.

For modules where allow_incremental_platform_api is set to 'true' (false
by default) the pattern is the same, however <version> is presumed to be
of the form MM.m, where MM aligns with the existing API level and m
signifies the incremental release (e.g. QPR).

Test: platform build check with both incremental & non-incremental API
      cd build/soong && go test ./java
