This commit approximately doubles the performance of til::enumset
and reduces it's binary footprint by approximately 1kB.
Most of the binary size can be attributed to exception handling.
Unfortunately this commit removes assertions that the given values are less than
the number of bits in the `underlying_type`. However I believe this to be a good
trade-off as the tests previously only happened at runtime, while tests at
compile time would be highly preferable. Such tests are technically possible,
however MSVC fails to compile (valid) `static_assert`s containing
`static_cast`s over a parameter pack at the time of writing.
With future MSVC versions such checks can be added to this class.
This change was initially discussed in #10492, but was forgotten to
be considered before it was merged. Since the work was already done,
this commit re-introduces the optimization. It's free!

## Summary of the Pull Request
This introduces a new TIL class that is equivalent in functionality to a `std::bitset`, but where the positions in the bitset are enum values. It also has a few additional methods allowing for setting and testing multiple positions at the same time. The idea is that this class could be used in place of the `WI_SetFlag` and `WI_IsFlagSet` macros when working with sets of flags.

## Validation Steps Performed
I've added a few unit tests that verify the behaviour of all the new methods that aren't part of `std::bitset`. I've also tried it out as a replacement for the `GridLines` enum used in the renderer, and confirmed that it has all the functionality needed to replace that cleanly.
