Kernel: Simplify Process factory functions

Browse source 
- Instead of taking the first new thread as an out-parameter, we now
  bundle the process and its first thread in a struct and use that
  as the return value.

- Make all Process factory functions return ErrorOr. Use this to convert
  some places to more TRY().

- Drop the "try_" prefix on Process factory functions.
