pw_sync_baremetal: Add simple mutex implementation

Adds a dummy mutex implementation for baremetal configurations.

The provided implementation makes a single attempt to acquire the
lock and asserts if it is unavailable. It does not perform interrupt
masking or disable global interrupts, so this implementation does
not support simultaneous multi-threaded environments including IRQs,
and is only meant to prevent data corruption.
