lib: Move __gem_context_create to common ioctl wrapper library.

This patch adds a context creation ioctl wrapper that returns the error
for the caller to consume. Multiple tests that implemented this already,
have been changed to use the new library function.

v2:
	- Add gem_require_contexts() to check for contexts support (Chris)

v3:
	- Add gem_has_contexts to check for contexts support and change
	  gem_require_contexts to skip if contests support is not available.
	  (Chris)

v4:
	- Cosmetic changes and use lib function in gem_ctx_create where
	  possible. (Michal)

v5:
	- Use gem_contexts_require() in tests and fixtures. (Chris)
