misra.py: Treat enum constants as constant known at compile time ( #2823 )

C89 standard defines enum members as enumeration contants at ch.
6.4.4.3, and they are always known at compile time.
This commit fix false positives for rule 18.8 (and possible other rules
that check "constentess") with enumeration members.

misra.py: Fix 12.3 FP for variables defined in headers ( #2773 )
...
When we include the header file with variables definitions, Cppcheck
will write `variables` entries with line numbers from the header to the
dump file.
If the line number in the header file and the source file are equal,
misra.py performs an additional check what leads to false positives.
Minimal example that demonstrates the problem:
`misra_fp.c`:
```c
void test_12_3_fp(void)
{
//Initialize the events queue
QEQueue_init(&me->deferred_event_queue, me->deferred_events_queue_buf, Q_DIM(me->deferred_events_queue_buf));
}
```
`misra_fp.h`:
```c
static const uint32_t timer_max_blocking_call_us;
```
This commit closes trac ticket 9874.
