[CIR] Fix parsing of #cir.unwind and cir.resume for catch regions

[wizardengineer]

1. Catch Entry Parsing: parseCatchEntry in CIRDialect.cpp now properly handles #cir.unwind attributes

2. Resume Operation: Fix record definition of cir.resume in order to handle locations correctly

Issue:

• error: expected '{' to begin a region when parsing catch [#cir.unwind {
• error: undefined symbol alias id when parsing cir.resume loc(#loc)

@bcardosolopes there's a Clang CIR Tests / Test clang-cir / Lit Tests (windows-2019) that fail, is it a false positive?

It says it got cancelled, not too sure why.

Also, thanks for taking your time to review this Bruno 😄
