Core/Metric: Add more metrics about World::Update() loop (#25098)

* Core/Metric: Add more metrics about World::Update() loop

* Add new Performance profiling grafana dashboard

* Add new cmake setting WITHOUT_METRICS that disables all metrics

As new metrics are added, someone might want to disable them if unused.

* Add more metrics about World::Update() loop

* Remove old performance profiling features

Remove "server set difftime" command, "-RecordUpdateTimeDiffInterval" and "MinRecordUpdateTimeDiff" worldserver config settings and their related code.
The whole UpdateTime class could be removed too.

* Update and rename 2020_07_99_99_world.sql to 2020_07_24_00_world.sql

(cherry picked from commit 3c0ac7302f902d1811d2c215217a3d701f8b5b19)
