MPSL low-latency callbacks

Functions
void	mpsl_low_latency_acquire_callback (void)
	Acquire low-latency settings to the system.
void	mpsl_low_latency_release_callback (void)
	Release low-latency settings from the system.

Detailed Description

Application-implemented callbacks invoked by MPSL on nRF54L Series devices. Use mpsl_low_latency_acquire_callback before time-critical MPSL work (for example around radio activity) and mpsl_low_latency_release_callback when that work is finished so the platform can relax NVM latency and related settings.

When time-critical events are back-to-back, MPSL may skip release between events and only call release after the last event; implementations must tolerate skipped intermediate releases (for example by counting acquires).
