The HLSL/MSL includes in data_builder.h appear unused, but gn was
flagging them as problematic when attempting to build with the
corresponding tint_build flags disabled.
module_clone_test.cc is dependent on the WGSL reader and writer, but
was not gated on the corresponding tint_build flags in BUILD.gn.
tint_unittests_transform and tint_unittests_glsl_writer were both
dependent on the WGSL reader/writer, so added it as an explicit
dependency.

The resolver now wraps sem::Expression objects with a sem::Load object
anywhere that the load rule is invoked. sem::Expression provides an
`UnwrapLoad()` method that returns the inner expression (or
passthrough, if no load is present), which is analaguous to
Type::UnwrapRef().
The logic for alias analysis in `RegisterLoadIfNeeded` has been folded
into the new `Resolver::Load` method.
Fixed up many transforms and tests. The only difference in output is
for a single SPIR-V backend test, where some IDs have changed due to
slight re-ordering of when expressions are generated.
There may be further clean-ups possible (e.g. removing unnecessary
calls to `UnwrapRef`, and simplifying places in the SPIR-V writer or
transforms that deal with memory accesses), but these can be addressed
in future patches.

We no longer need the UnwindDiscardFunctions transform for HLSL, which
