  [Clang] Fix error recovery for default arguments (#208868)

Fixes  #205718 
### Description
This PR fixes an issue where Clang incorrectly skips the creation of a
parameter when an error occurs in a default argument that involves a GNU
statement expression (`({ ... })`).

Previously, if the default expression evaluation failed within a
statement expression, the error recovery was not handled properly,
leading to the parameter being dropped. This fix ensures that the
parameter is correctly created and error recovery proceeds as expected.



### Testing
Added/Updated test cases in
`clang/test/SemaCXX/default-arg-error-recovery.cpp` to cover invalid
default arguments inside statement expressions.
