Handle complex cases in Inspector::GenerateSamplerTargets

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.
