Literal handling improvements (#1202)

* WIP: 64 literal diagnostic and truncation.

* Improve how integer truncation is handled/supported.
Added literal-int64.slang test.
Set a suffix on all literals.
Fixed problem on C++ based targets where l suffix was not the same as int() cast. So on C++ derived emitters, int() is used instead of l suffix to have same behavior across targets.

* Add literal diagnostic testing.

* Allow lexer to lex - in front of literals.

* Fix lexing and converting int literal with -.

* Too large small values of floats become inf.
Handling writing inf types out on different targets.
Add function to deterimine if a float literals kind.

* Roll back the support of lexer lexing negative literals.

* Fixed tests broken because of diagnostics numbers.
Improved _isFinite

* Fix compilation on linux.

* Fix problem with abs on linux - use Math::Abs.

* Fix typo.

* * Improve warnings for float literals zeroed
* Improved 64 bit type documentation
* Handle half
* Improved comments
* Fixed tests broken
* Use capital letters for suffixes.

* Make default behavior on outputting a int literal that is an 'int32_t' is cast (not suffix) to avoid platform inconsistencies.
Improve documentation for 64 bit types.
Make tests cover material in docs.

* Fixed tests.

* Rename FloatKind::Normal -> Finite

* Fix half zero check.
