MDL-44977 tool_profiling: set xhprof default settings

Set xhprof default settings, even if xhprof is not installed.
If xhprof is not installed, hide profiling admin settings,
else show them.
This is needed, because if xhprof is installed, then it will
fail all non-js behats which navigate to setting under
site administration, as profiling settings get displayed on
default admin page.

Replace a hardcoded div.notifyproblem with a API call that,

as that might cause problems for themers who expect it to be
used consistently with the API.

MDL-44844 core: Fix custom menu navigation

Atto introduced a rule to hide all Nodes with the yui3-menu-hidden class
but this rule is too general and applies to non-atto content too.

As a result, when loading the menu and during the XY calculation, the
native Element.getBoundingClientRect() function was returning a bounding
box size of 0 because the Node was not visible and the node was being
hidden from view when it was later made visible.
