drm/vmwgfx: Add a mksstat counter for cotable resizes

Browse source

There's been a lot of cotable resizes on startup which we can track
by adding a mks stat to measure both the invocation count and
time spent doing cotable resizes.

This is only used if kernel is configured with CONFIG_DRM_VMWGFX_MKSSTATS
The stats are collected on the host size inside the vmware-stats.log
file.
