c: Implement C2Y N3298 - Introduce complex literals [PR117029]
The following patch implements the C2Y N3298 paper Introduce complex literals
by providing different (or no) diagnostics on imaginary constants (except
for integer ones).
For _DecimalN constants we don't support _Complex _DecimalN and error on any
i/j suffixes mixed with DD/DL/DF, so nothing changed there.
