[lldb][test] 1 - Don't do test-replication for gmodules debug_info variant

Currently, by default LLDB runs an API test with 3 variants,
one of which, depending on platform, is `gmodules`. However,
most tests don't actually make use of any specific `gmodules`
feature since they compile a single `main.cpp` file without
imporint types from other modules.

Instead of running all tests an extra time with `-gmodules`
enabled, we plan to test `gmodules` features with dedicated
API tests that explicitly opt-into compiling with `-gmodules`.
One of the main benefits of this will be a reduction in total
API test-suite run-time (by around 1/3).

This patch adds a flag to `debug_info_categories` that indicates
whether a category is eligible to be replicated by `lldbtest`.

Keeping `gmodules` a debug-info category is desirable because
`builder.py` knows how to inject the appropriate Makefile flags
into the build command for debug-info categories already. Whereas
for non-debug-info categories we'd have to teach it how to. The
category is inferred from the test-name debug-info suffix currently.

introducing a concept (hah!) of "ContainsErrors" to the Satisfaction
types, which causes us to treat the candidate as non-viable.

However, just making THAT candidate non-viable would result in choosing
the 'next best' canddiate, which can result in awkward errors, where we
start evaluating a candidate that is not intended to be selected.
Because of this, and to make diagnostics more relevant, we now just
cause the entire lookup to result in a 'no-viable-candidates'.

This means we will only emit the list of candidates, rather than any
cascading failures.

[flang] Lowers calls to procedure with CONTIGUOUS assumed shape dummies

Copy-in/copy-out was not triggered when calling a procedure with a
CONTIGUOUS assumed shape. The actual argument must be copied-in/out
if it is not contiguous.
The copy-in/copy-out takes care of argument optionality, and uses a
runtime check in order to only do the copy if the actual is not
contiguous at runtime.

This was already implemented for explicit shape dummy arguments. This
patch takes advantage of this implementation to deal with the copy-in
copy-out aspects. It only need add code to deals with wrapping the
created bare contiguous address into a fir.box (runtime descriptor),
taking care of the optional box aspects.

Using this existing code is only possible for actual argument that can
be passed via a bare address. Add a TODO for polymorphic entity, PDTs
and assumed rank where the existing copy-in/copy-out code may fail
(these copies are more complex) and that cannot be tested currently.
