This change adds an override for Transform::ShouldRun() for many of the transforms that can trivially detect whether running would be a no-op or not. Most programs do not require all the transforms to be run, and by skipping those that are not needed, significant performance wins can be had.
This change also removes Transform::Requires() and Program::HasTransformApplied(). This makes little sense now that transforms can be skipped, and the usefulness of this information has been severely reduced since the introduction of transforms that need to be run more than once.
Instread, just document on the transform class what the expectations are.

This transform converts all separate texture/sampler references
in a program into combined texture/samplers. This is required for GLSL,
which does not support separate texture/samplers.
As input, the transform requires a map from the unique sampler/texture
pairs previously gathered by the Resolver to strings, which will be
used as the names of the newly-generated combined samplers. Note that
binding points are unused by GLSL, and so are set to (0, 0) with
collision detection disabled.
All function signatures containing textures or samplers are rewritten,
as well as function calls and texture intrinsic calls. For texture
intrinsic calls, a placeholder sampler is used to satisfy the subsequent
Resolver pass (GLSL texture intrinsics do not require a separate sampler,
but WGSL intrinsics do). The placeholder is also used if the shader
contains only texture references (e.g., textureLoad).

Fold both PromoteInitializersToConstVar and VarForDynamicIndex into this
new transform, with a config to enable either type of transformation.
This is almost a no-op change, except that VarForDynamicIndex required
ForLoopToLoop, while this tranformation in PromoteInitializersToConstVar
converts for-loops only as needed, so it doesn't do so when the
expression is in the for-loop initializer.
This transform will be extended to handle ensuring order of execution of
expressions.

Tint has been used to convert all the deprecated attributes to the new style. In doing so, comments have been stripped. These are not massively important for the benchmarking.
Bindings have also been adjusted to be sequential and unique so that the MSL backend doesn't have to deal with binding remapping.
Existing benchmark files that used an underscore '_' have been renamed to use a dash '-' instead, to match the new files.
