Antonio Maiorano 06844a5e24 tint/hlsl: remove [loop] attribute on all loops
I added the forcing of the "loop" attribute to all loops to address FXC
failing on uniformity errors related to gradients in loops. Since then,
Tint now implements UA and it recently became an error, so we no longer
need this hack. As a result, FXC is now better able to cope with loops
that it determines executes 0 times.

Most e2e tests are affected because so many use loops, but 27 tests that
were previously failing are now passing with this change:
