qwerty is auto probed, making HMDs that are not auto probed always take precedence.
When setting QWERTY_ENABLE=1 the intent is usually to exclusively use qwerty.
Therefore we default to disabling all other drivers when this variable is set.
To make the old behavior of adding qwerty devices with lower priority than actual
devices, the variable QWERTY_COMBINE=1 is introduced.

It's not worth introducing a new error code for this case, just
return XRT_ERROR_VULKAN.

In release builds asserts will be disabled, so we should try to handle the
assert cases reasonably.
This commit fixes several unused variable warnings when asserts are disabled.
The hardcoded value 32 was actually wrong and caused a warning

The STOPPING state has two possible follow up paths:
STOPPING -> IDLE -> READY
STOPPING -> IDLE -> EXITING
After EXITING, the application must call xrDestroySession; there is no meaningful
session state after EXITING.
To go to the READY state again, the application should first create a new session.
Applications that are lazy and drain the entire event queue and only handle
the last encountered state would be affected by "skipping" the EXITING state.
