Use new checkPermissions shorthand in api calls

[colemanw]

Overview

This does a simple find/replace to update internal api calls to use the new shorthand from #17834.

Before

Foo::get()->setCheckPermissions(FALSE)...

After

Foo::get(FALSE)...

Comments

This doesn't update every single instance but I wanted to keep the regex simple & safe.
