Improve sizer flags validation in the XRC schema.

Browse Source 
Validate flags for 1D horizontal and vertical sizers and grid sizers
separately to allow checking for invalid flag combinations.

Also try to make the regex patterns used in the schema itself and the error
messages generated when matching them fails slightly more readable.
