Deprecate 'c', 'C' prefix for octal literals, fixes #8082 (#8178)

Browse source 
* deprecate `0c`, `0C` prefix for octal literals

Deprecates the previously allowed syntax of `0c` and `0C` as a prefix for
octal literals to bring the literals in line with the behavior of
`parseOct` from parseutils.

* add `msgKind` arg to `lexMessageLitNum` for deprecation messages

* change literal tests to check all valid integer literals

Also adds the `tinvaligintegerlit3` test to test for the (still)
invalid `0O` prefix.

As can be seen in the productions, numerical constants can contain underscores
for readability. Integer and floating point literals may be given in decimal (no
prefix), binary (prefix ``0b``), octal (prefix ``0o`` or ``0c``) and hexadecimal
prefix), binary (prefix ``0b``), octal (prefix ``0o``) and hexadecimal
(prefix ``0x``) notation.
There exists a literal for each numerical type that is
