Fix getStatus for math-mutate and math-display

Browse Source 
Those two functions used two different hackish and buggy
implementation to know when the function is disabled. Replace that by
asking the containing inset whether it accepts inserting display math
inset.

Fixes bug #10033.

- Display the correct column alignment and a better column spacing in AMS
environments (bugs 1861, 9908).
- Disable properly toggling math diplay in places where it is not
possible (bug 10033).
- Fix horizontal scrolling feature when inside a collapsable inset
with several paragraphs.
