GraphemeData: define error set as mem.Allocator.Error

The reader is a static embedded file. All of the reads are either a
readInt or a readAll into a previously allocated buffer. This function
should not ever fail at runtime with a read error. Make all read errors
unreachable, leaving only allocation errors as the error set.
