feat: Create generic pow implementation

[enitrat]

Feature Request

Create a generic implementation of pow over type T to avoid unnecessary code duplication. This will allow using all integer types in exponentiation operations.
This can not be performed natively for wrapping_pow as we can't use generics with libfuncs such as u256_overflow_mul. That would require adding a WrappingMath trait, but it's not a priority for now

Important update: we are gathering some bugs in the Kakarot v0 codebase, we need to make sure each issue and each PR in Kakarot-ssj is aware of the lists of known bugs. Look at this tracking issue everytime you take an issue and check your issue isn't targeted by a known bug. Will add this reminder in many places to make sure we keep track of known bugs.
