Cycles: several small fixes and additions for MSL

This patch contains many small leftover fixes and additions that are
required for Metal-enablement:

- Address space fixes and a few other small compile fixes
- Addition of missing functionality to the Metal adapter headers
- Addition of various scattered `__KERNEL_METAL__` blocks (e.g. for
  atomic support & maths functions)
