This code was implicitly assuming that all resources it was looking
for would be directly referenced at the intrinsic callsite, and not
passed via function parameters.
This was causing a crash in more complex cases.
The inspector code has been updated to handle cases where the
resources are not being directly referenced.
Unneeded calls to GenerateSamplerTargets() are removed.
Utility function GetOriginatingResources() is added to handle walking up
call sites to resolve resources.
Text shader based test runner is added to the Inspector tests to make
expressing complex tests easier.

The continuing block can exit the loop in very constrained ways:
When a break statement is placed such that it would exit from a loop’s
§ 7.3.8 Continuing Statement, then:
- The break statement must appear as either:
- The only statement in the if clause of an if statement that has:
- no else clause or an empty else clause
- no elseif clauses
- The only statement in the else clause of an if statement that has an
empty if clause and no elseif clauses.
- That if statement must appear last in the continuing clause.
By design, this allows a lossless round-trip from SPIR-V to WGSL and
back to SPIR-V. But that requires this special case construct in WGSL
to be translated to an OpBranchConditional with one target being
the loop's megre block (which is where 'break' branches to), and the
other targets the loop header (which is the loop backedge). That
OpBranchConditional takes the place of the normal case of an
unconditional backedge.
Avoids errors like this:
continue construct with the continue target X is not
post dominated by the back-edge block Y

Add `transform::DecomposeStridedMatrix`, which replaces matrix members of storage or uniform buffer structures, that have a [[stride]] decoration, into an array
of N column vectors.
This is required to correctly handle `mat2x2` matrices in UBOs, as std140 rules will expect a default stride of 16 bytes, when in WGSL the default structure layout expects a stride of 8 bytes.
