Fix incorrect resolve of specialization instance (#6162)

* Fix incorrect resolve of specialization instance

While checking the uninitialized variables, we were not resolving the
specialized instance correctly. This commit repeats the resolve while
the result is a specialization instance. A new test is added for this:
  tests/diagnostics/uninitialized-generic.slang

After the problem is fixed, it revealed another problem in existing
tests:
  tests/compute/nested-generics2.slang
  tests/diagnostics/uninitialized-local-variables.slang

When a struct has a member variable whose type is a generic type,
we cannot iterate over its member variables yet, because the type
is unknown until the generic function/struct is specialized. We will
have to give up checking for these cases.
