feat: Add missing parameters to InlineTextStyle (#3146)

Add missing parameters to `InlineTextStyle`, such as `height` and
`shadows`.

Without this, it is not possible to configure such parameters in the new
text rendering pipeline. Since the other parameters are 1:1 to Flutter's
`TextStyle`, these missing fields seem to have been just an oversight.
