[OpenThread] Increase SRP service count (#19900)

We assumed that MAX_FABRICS + 1 slots for SRP services is
enough, but to pass Pre-SVE tests it must be possible to
open the commissioning window after having been commissioned
to MAX_FABRICS fabrics, and the commissionable instance name
changes on opening the window.

Therefore, if the extended discovery is enabled, two slots
for the commissionable services are needed for a short time:
the old service to be removed and the new service to be
added.
