[Tools] Diagnose coarse-fences invocation without HAL device (#24274)

Coarse-fences invocation requires the caller to provide wait/signal
fences backed by a HAL device. If module dependency resolution did not
create a HAL device, the invoked function is not declaring the HAL
dependency needed to signal or fail its completion fence.

Fail with a specific diagnostic before trying to create the signal fence
instead of falling through to a null-device failure.
