Related: fdo#81457 quadratic time required when setting a11y name

when calling SetAccessibleName GetAccessibleName is called
in order to send a name changed a11y event. Getting an Accessible
Name is very slow in a non-layout aware widget because it scans
for a "nearby" label and there is none in this widget, but it
has a huge pile of other widgets to iterate over.

call add_mnemonic_label before hand to cut off that entire
branch.

While we're at it, only call InitControl to adjust to a new
width if the new width is different from the old width
