Improve portability and fix dynamic CPU entry/exit in gedf_env

Dynamic CPU entry/exit changes:
- Fix build with CONFIG_RELEASE_MASTER
- Migrate gedf_env release timer when a core is suspended
- Fix race condition in gedf_env core resume
- Add documentation
- Allow for gedf_env_suspend() and gedf_env_resume() to be called
  on CPUs that have already been suspended or resumed. (They do
  nothing in those cases.)
Portability:
- Allocate space in `gedf_reservation_environment` using
  `num_online_cpus()` rather than `NR_CPUS`. Otherwise the stack
  frame can overflow when `NR_CPUS` is large.
- Assign `plugin_state` from the plugin rather than the extended
  reservations code to support other uses of `plugin_state`.
Misc:
- Improve robustnesss of `gedf_env_is_np()`
- Don't memset with 0 memory already zeroed-out by `kzalloc()`
- Use GFP_ATOMIC for allocations when in a scheduling context
