Make character tables more readable

[ravenblackx]

Commit Message: Make character tables more readable
Additional Description: Character tables have been created as an array of binary values with comments. This PR uses modern constexpr to generate them with code, so they're still constexpr and performance should be identical, but the code is more readable, no need to manually read every bit to see what's happening.
Risk Level: Should be no change, but there is some risk that I missed or added one bit. The existing test coverage is fairly aggressive with checking every character, so I think the risk of that is low.
Testing: Added some tests that the constexpr generators are generating the expected outcomes.
Docs Changes: n/a
Release Notes: n/a
