Add APIs in Silk.NET.Maths that are explicitly checked or unchecked

[Perksey]

Summary of feature

Currently, Silk.NET.Maths just respects the underlying language rules with regards to overflows, underflows, checked contexts, and unchecked contexts. We should add methods that are explicitly unchecked or checked such that the user knows what a method will actually do.

Comments

For example

• Scalar.CheckedAdd(a, b)
• Vector.CheckedMultiply(a, b)
  etc

Does this have a proposal?

This won't require a proposal as there's probably little to debate here so long as they mirror the ambiguous APIs but with a different API

[Perksey]

Discussed in Working Group meeting (because why not) 19:35 UTC

• Doesn't make sense to have explicitly checked APIs
• Could just make all APIs unchecked?
• csharplang#4665, default will be unchecked

Consensus
Make all APIs all unchecked, with the provision that it is documented in some capacity.

Should already be unchecked, issue closed.

Action Item
Make a test for this behaviour.
