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.

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.
