Do not print errors in _coerce when "JustTrying". (#7064)

* Do not print errors in _coerce when "JustTrying".

While figuring out which generic-overload works best, `_coerce()` is
printing errors and Slang compilation terminates prematurely.

When `TryCheckGenericOverloadCandidateTypes()` is calling `_coerce()` in
"JustTrying" mode, the error messages should be snoozed.

The following logic shows the intention of how to silence the error
messages, but the chain of `sink` was broken in the middle and
`_coerce()` was using `getSink()` from the SemanticVisitor.

 val = ExtractGenericArgInteger(
   arg,
   getType(m_astBuilder, valParamRef),
   context.mode == OverloadResolveContext::Mode::JustTrying ? nullptr : getSink());

* Use tempSink when available.
