[Android] Fix shadows size in clipped views (#11603) Fixes #11578

* Fix shadows clipping views

* Fix build errors

* Capture and cache Context usage

We've found Context can be a bit expensive to get in a large frequency of calls (#8001), so we can avoid this by capturing and caching the instance.

* Removed duplicated test

* Revert latest changes
