[roll third_party/pigweed] pw_multisink: Lock multisink operations

Guards all multisink transactions with a lock. The new configuration
option PW_MULTISINK_LOCK_INTERRUPT_SAFE allows the project to select
the type of lock used to guard transactions. By default, it is enabled
and makes use of an interrupt spin-lock. If disabled, a mutex is used
instead.
