Handle even more include in enum cases

The solution in d3ed7dac8a was needlessly
complicated, and broke a valid use case.
The issue of no identifier being available to parse after the include
has been processed can instead be solved by moving the test for the
closing brace after the include processing.

Fixes: QTBUG-94790
Pick-to: 6.2 6.1 5.15
