drm: Move drm_timeout_abs_to_jiffies() to drm_timeout.c

drm_timeout_abs_to_jiffies() began as a static helper inside the syncobj
wait implementation and was later exported in place, so that it could be
called by multiple drivers (e.g. panfrost, lima, tegra and accel
drivers). All of them reach it through drm_utils.h.

Give it a file of its own, so that timeout conversion helpers have a
home, which will be useful when we add new timeout handlers. Also create
a drm_timeout.h header to host all timeout-related helpers.

The function was moved to the new file as it is, including the use of
"signed long" as the return type. Note that the return and parameters
types should be reconsidered in the future to better represent the
non-negative nature of a timeout.

No functional change.
