Implement support for regular scaled buffer formats

`SCALED` formats are essentially the same as `INT` formats, but
converted to floating-point. Thus we can trivially support all the ones
that already had a corresponding supported `INT` format. Concretely,
this change adds support for 1-, 2-, and 4-element formats with 8-bit
and 16-bit  components.
