Make m_registeredTimerLock an UnfairLock to prevent priority inversion

Reviewed by Ben Nham.
Similar to m_nextIterationLock in https://github.com/WebKit/WebKit/pull/55668,
m_registeredTimerLock
is another RunLoop WTF::Lock that could lead to priority inversion since both
low and high
priority threads can acquire it.
So as a defensive measure, we change m_registeredTimerLock from a WTF::Lock to
UnfairLock to enable priority inheritance.
This is similar to the fix for m_incomingMessagesLock in
https://commits.webkit.org/281223@main.
