atbrakhi 3c8c46d32f devtools: implement pause and resume in debugger (#42580)
When a breakpoint is hit, the script thread now pauses execution and
notifies devtools clients with a "paused" event. The script
thread enters a loop that processes devtools messages until
a Resume command is received.

This change does not implement manual pause

Testing: Added new test
Fixes: part of https://github.com/servo/servo/issues/36027
