Ben Clayton 03de0e83ae Move tint::transform::Robustness to a santizier transform
There's no good reason for this to be public.
Move it into the writers, and expose a 'disable_robustness' option to
turn it off. This can be expanded to hold more fine-grain control in the
future.

Ben Clayton 619f9bd639 tint/transform: Fix ICE when combining polyfills
There's a reason the overload of `ctx.Replace()` that takes a pointer to the replacement is deprecated - it doesn't play well when used as part of another replacement.
Switch to using the callback overload of Replace() to fix bad transform output.

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:

Ben Clayton 7d34de88f1 tint/test-runner: Split expectations for FXC and DXC
Change tint's `--fxc` flag to take the path of the FXC compiler DLL.
Have tint attempt to validate with both FXC and DXC if `--validate` is
passed.

Fix the 'dirsWithNoPassExpectations' logic which looks like it got
broken with the tint -> dawn merge. It also incorrectly applied
filepath.FromSlash() on windows.
