Rewrite Enum and add {ISpanFormattable}.TryFormat (dotnet/runtime#78580)

* Add generic Enum.TryFormat method

* Rewrite Enum using generic specialization per underlying type

Also revises the shape of the newly added Enum.TryFormat method and fixes tests accordingly.

* Use Enum.TryFormat in interpolated string handlers

* Implement ISpanFormattable on Enum

* Use generic Enum methods in more places

* Replace Unsafe.As with unmanaged pointers where possible

Reduces cost of the generic methods

* Simplify Enum_GetValuesAndNames QCall, fix handling of floats and doubles

This change avoids allocation of the temporary ulong[] array during EnumInfo initialization

Fixes dotnet/runtime#29266

* Fix mono's GetEnumNamesAndValues, and make ToObject handle float/double as well

* Fix perf gap and polish

* Undo update of Enum.GetTypeCode to include float/double

* Address PR feedback

* Accomodate net8.0 TFM update

* Fix InvalidCastException from GetEnumValues on mono when dealing with bool-based enums
