[INETRNAL] sap.m.Popover: Prevent some of trashing layout cases in
adjustPositionAndArrow method

Decreased the number of layout trashing in Popover. When Popover is opened
a number of style calculations occurs. Some of them need to be checked
after another style is applied. However some of them could be calculated
before any other styles are applied.
