Switch the default severity for all uniformity violations to errors.
We now have an opt-out mechanism for deriviative operations (via
diagnostic filters), and a `workgroupUniformLoad()` builtin for
compute shaders.

When used with the SPIR-V reader, this will insert a module-scope
diagnostic directive to suppress uniformity violations for derivative
operations.

Add additional `RequiredToBeUniform` nodes for each severity
level. When processing a call to a derivative builtin, look up the
severity from the semantic info for that AST node, and add an edge to
the corresponding `RequiredToBeUniform` node.
Propagate the severities to the callsite and parameter tags for a
function that contains a builtin.
Traverse that graph from each `RequiredToBeUniform` node to look for
violations at each severity level, starting with the most severe. Only
stop the analysis if an error is found, otherwise report the violation
and keep going.

Each sem::Node has a map which stores the diagnostic modifications
applied to that node. The sem::Info class provides a query to get the
diagnostic severity for a given AST node, by walking up the semantic
tree to find the tightest diagnostic severity modification. The
default severity is used if it was not overridden.
This allows components outside of the Resolver/Validator to determine
the diagnostic severity while walking the AST, which is required for
the uniformity analysis.

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.
