Subject: [PATCH] vulkan: make VK_TIME_DOMAIN_CLOCK_MONOTONIC_RAW_EXT
 conditional

Only advertise VK_TIME_DOMAIN_CLOCK_MONOTONIC_RAW_EXT if CLOCK_MONOTONIC_RAW
is defined.  Fixes the build on OpenBSD which has CLOCK_MONOTONIC but not
CLOCK_MONOTONIC_RAW.

Fixes: 67a2c1493c0 ("vulkan: Add VK_EXT_calibrated_timestamps extension (radv and anv) [v5]")
