lib: Add gem_userptr and __gem_userptr helpers

This patch moves userptr definitions and helpers implementation that were
locally in gem_userptr_benchmark and gem_userptr_blits to the library, so other
tests can make use of them as well. There's no functional changes.

v2: added __ function to differentiate when errors want to be handled back in
the caller; bring gem_userptr_sync back to gem_userptr_blits; added gtkdoc.
v8: remove local_i915_gem_userptr from gem_concurrent_all.c to use the global
helpers instead.
