Enable -Wexit-time-destructors for all in-tree library targets and
update process-lifetime library statics so they no longer register
exit-time destructors. Long-lived caches, lookup tables, singleton
registries, and generated constants now use NeverDestroyed or leaked
references where the data is intended to live until process exit.
Update LibWeb, LibLine, and the binding generators so regenerated
sources follow the same rule instead of reintroducing destructed
statics.
This macro outputs the time taken to reach the end of the current scope
to the debug console. It also shows the average time, total cumulative
time and the total number of calls.
It is also possible to limit the amount of debug output using
`REPORT_TIME_EVERY(name, n)` to only print every `n` calls.
