[TASK] runTests.sh: Add phpstan and docBlockCheck

Allows:
* Build/Scripts/runTests.sh -s docBlockCheck
* Build/Scripts/runTests.sh -s phpstan

These two have been added to bamboo with #89023, but not to
runTests.sh.

phpstan is tuned a bit to create it's cache in .cache rather
than ephermal /tmp to survive between host reboots.
Additionally the number of max CPU's is restricted in phpstan
to be a better neighbor on local dev machines and on CI.

Resolves: #93367
Related: #89023
Releases: master, 10.4
