[sdb] Fix state initialization of suspended threads to work when the debugger thread is not attached. Fixes #34750

The problem happens because thread_interrupt runs in the debugger thread (suspend initiator).

thread_interrupt then calls mono_thread_state_init_from_monoctx which collects the state of the current thread
which is definitely not what we wanted.

There used to be some compensation code after calling mono_thread_state_init_from_monoctx to actually init the state properly.
This is why it worked, at all.

Thew problem is that the debugger thread now might not attach at all under some circumstances, which would trigger
mono_thread_state_init_from_monoctx to return FALSE and trip into the assert.

The fix is to simply not use mono_thread_state_init_from_monoctx at all, just copy the state from data. This fix has the
bonus of getting the domain correctly.
