Improve window style cache
The cache replied on AttributeCache, but because it caches entire
TypedArray (it may be big), it only preserves a few packages.
Then it may need to read from package resources frequently, which
may add latency when starting activity:
AttributeCache > createPackageContextAsUser
> createResources > getResources
> createApkAssetsSupplierNotLocked > loadApkAssets
By only storing the used attributes, the size of cache becomes
very small which can be preserved per boot session.
