check-flagged-apis: parse API signature files
Teach check-flagged-apis to extract flagged APIs from API signature files.
To keep things simple, only consider fields for now: support for classes
and methods will be added in a later CL.
Note: `m frameworks-base-api-current.txt` will generate an API signature
file that includes both the platform and mainline APIs.
