WL#9625: Enable pfs memory instrumentation by default
Affects: Server-8.0 — Status: Complete — Priority: Medium
In MySQL 8.0 we should enable pfs memory instrumentation in the default configuration of the server. This is important because the accounting is incorrect if instrumentation is enabled after server start (i.e. you could get a negative balance from missing an allocation, but catching a free).

FR1) The compiled default configuration of the MySQL Server is changed to: performance-schema-instrument='memory/%=COUNTED'
