Make types augmentable from the sources, not the build-types transform

Revert convertTypeAliasesToInterfaces to its original form. Get the same
emitted types from the Flow sources instead.

Styles: rename ____ViewStyle_Internal, ____TextStyle_Internal and
____ImageStyle_Internal to ViewStyle, TextStyle and ImageStyle.
StyleSheet now re-exports each name unchanged, with no alias.

Props: 11 annotated types still emitted members in the interface body.
Each one now moves its inline members into a private <Name>Core alias.
All members are inherited through the extends clause, so a module
augmentation can refine them.

ImagePropsBase and ImageBackgroundProps declare members that shadow keys
of the type they spread. An explicit Omit removes those keys, because a
Flow spread of an optional property unions the two types instead of
replacing the member.
