  [clang] Fix a crash with parenthesized aggregate initialization and base classes

When calling InitializeBase(...), TryOrBuidlParenListInit(...) needs to
pass in the parent entity; otherwise, we erroneously try to cast
CurContext to a CXXConstructorDecl[0], which can't be done since we're
performing aggregate initialization, not constructor initialization.

Field initialization is not affected, but this patch still adds some
tests for it.

Fixes 62296
