Dependency injection of AssetProviders into ApkAssets

Creates ApkAssets creation methods that allow an AssetsProvider to be
specified.

During idmap verification and creation, idmap2 currently opens the
target package and overlay package several times:
1) When the crc of the package is calculated in idmap2 verify
2) When the manifest of an overlay is parsed
3) When an ApkAssets is opened.

Opening large zip files (like framework-res.apk) is slow. If we opened
the zip one time as an ApkAssets, the resources.arsc would have to be
parsed (which means mmaping/unmapping and touching a lot of
resources.arsc pages). This would cause idmap2 to preform unnecessary
work just to check the crc of some files.

This change allows a ZipAssetsProvider to be created and then moved
for the creation of an ApkAssets. The zip file only needs to be opened
once and the resources.arsc is not parsed until reading resources is
actually necessary.
