Fix type for StyleSheet.compose()

Browse Source 
Summary:
This was flagged when typechecking the existing examples. The current type enforces that both stylesheets overlap, meaning composed stylesheets with distinct props cause a typechecking error. This changes the signature so that each style can be different, and the intersection type of the two is returned.

Changelog:
[General][Fixed] - Fix type for `StyleSheet.compose()`
