fix(menus): Fix menu positioning/animation

Since v3.0.0-rc.21, the column/grid menu animation slides down from
above the grid, but it is visible the entire time. This causes the
animation to appear clunky. This has been resolved by setting `overflow:
hidden` on the menu.

Fixes #3436, #3921, #3978.

Showing/hiding the menu can seem slow. The menu animation has been sped
up as well, and when it is hidden, the animation is now twice as fast.

Previously, to calculate the menu position, the width of the menu needed
to be calculated, which meant calling `repositionMenu` twice - once when
first opening the menu, and again after the menu is visible to allow the
width of the menu to be determined. This also meant there was always a
"shift" when the menu was first opened (as a default width of 170px was
used until the actual width of the menu could be determined. This
implements the CSS trick `right: 100%` so the width is not needed when
determining the menu's position, meaning the menu can be opened much
more smoothly and without needing to call `repositionMenu` twice.

Fixes #6587.
