[TableGen] Ignore fake args for parsing-related arg counts.
We should complain about the following:
```
void foo() __attribute__((unavailable("a", "b")));
```
Instead, we currently just ignore "b". (...We also end up ignoring "a",
because we assume elsewhere that this attribute can only have 1 or 0
args.)
This happens because `unavailable` has a fake enum arg, and
`AttributeList::{getMinArgs,getMaxArgs}` include fake args in their
counts.
