[srp-server] add new otSrpServerAddressMode for faster start up (#11180)

Browse Source 
This commit adds a new option in `otSrpServerAddressMode` as
`OT_SRP_SERVER_ADDRESS_MODE_UNICAST_FORCE_ADD`. This allows faster
SRP server start up by bypassing the Network Data publisher and
adding the "SRP/DNS unicast" entry directly to Network Data upon enabling
of the SRP server, regardless of how many other similar entries are
present.

This option is intended for testing and specific situations. A warning
is added to indicate that using this option will make the device
non-compliant with the Thread specification.

The unit test `test_srp_server` is updated with a new test case to
validate the new `AddressMode` and its related behavior.
