Adds a per-device check for a 'best' queue family to
use for present timing, rather than always using index 0.
wsi_ext_present_timing holds resources (such as the command
buffer) per queue family, rather than supporting only one. However,
currently, only one queue family is supported at a time.
In future, we can hook vkGetDeviceQueue calls to map
VkQueues to their family index. Doing this will transparently
give present timing support for multiple queue families.

Introduce util::mutex, util::recursive_mutex
and util::unique_lock; switch WSI layer call sites to it.
All locks are acquired via try_lock(), no system_error leaks.
