Set the context menu when first creating the popup,
not only when refreshing it.
Previously `Context::wm::menu` was set when a popups draw function ran
after being tagged RGN_REFRESH_UI, however the first time the draw
function ran this would be null. Ensure this is set in both cases
so logic that requires accessing the popup region can rely on it
being set.
Needed so the splash region is always accessible to implement #120612.
When we open dropdown (and context) menus we often show "Press spacebar
to search..." or "Type to search..." in the status bar. The status text
is set when menus are opened, and cleared when closed, but this means
that they are cleared when closing a submenu. This PR corrects this to
only clear then the base menu is freed.

Remove all BLF "_ex" versions of functions by using default arguments.
These functions only differ by having an optional argument that can
return extra details about the result of the operation. This PR just
make these part of the main function as optional arguments with default
values - all nullptr.
