layers:Add read/write mappings for AMD draws

These extended draw types were added without updating the read/write
flag LUT. Doh! Initially adding data as copies of matching non-AMD cmds
which should work. Added comments to double-check and make sure those
are the correct flags.

Also added a magic number entry at the end of the LUT CommandToFlags
array and a static_assert to make sure this array is correctly sized at
compile time.
