Time: Remove static from function local constexpr variable

Browse source 
Problem:
- Function local `constexpr` variables do not need to be
  `static`. This consumes memory which is unnecessary and can prevent
  some optimizations.
- C-style arrays are not as safe as AK::Arrays and require the user to
  specify the length of the array manually.

Solution:
- Remove `static` keyword.
- Change from C-style array for AK::Array.
