Make sure ImmutableStylePropertySet uses the new 16 bits size of StylePropertyMetadata.
We know that StylePropertyMetadata is 16 bits so we can use uint16_t as the type for the bitfields so that sizeof(StylePropertyMetadata) is equals to 2 bytes.
Cleanup two casts not necessary at the same time.
This should save up ~1.8Mb on Apple membuster test.
