Make default output of run command less noisy
When VK_EXT_debug_report is available, crucible run
prints a lot of
information and debug messages. Change it to by default print only
the warnings and errors, and provide an --extra-report
option to get
all messages.
The info messages include listings of all available extensions which makes the output of very noisy.
Also includes a separate patch to clean up VK_EXT_debug_report setup.
