utf8.h Swap which definition is the base
The GOT defines are now the principal ones, and the ALLOW ones are
changed to be in terms of the GOT. This seems right to me, as the GOT
ones are the ones anyone might actually care about. (The ALLOW ones are
for weird cases.) More importantly this makes the next commit make more
sense.

utf8.h: Define flags in terms of bit positions
This commit creates new #defines for the bit positions for the flags
that get passed to various functions that deal with UTF-8 input, and
then redefines the flag bits as the positions shifted to the proper
place.
There should be no change in the code generated by this.

Perl_utf8_to_uv_msgs_helper: Use bit pos in switch()
The previous commit #defined the bit position of various flag bits.
This commit changes to use those as cases in a switch(), rather than the
shifted values. This results in better generated code as the cases
now reduce to: case 0: case 1: case 2: ...
as opposed to previously: case 1<<0: case 1<<1: case 1<<2: ...
clang and gcc were unable to see the pattern previously but now are.
