The default hotkey is Ctrl+L, as this is not bound by
default in the FP or symbol editor, and it is the hotkey
that is used to focus the address bar in web browsers,
which is a similar kind of action.
This splits the tool into two separate tools: by center and
by even gaps. Previously, this was automatically decided, based on
if the items could have any gaps between them. This was unintuitive
as it would appear to arrange by centre point sometimes but not others.
When items aren't all the same width, the results can then be very
different, based only on the starting positions.
The new behaviour is to have a dedicated tool for each, which echos
how graphical programs like Inkscape manage this.
The by-gaps method is then extended to work for overlapping items
(when items overlap, the overlaps are made equal). The logic is
centralised in kimath/geometry, and some QA is added. This should
make it easier to extend to eeschema, for example.
This also (attempts to) address some rounding issues which could
cause minor, but compounding, errors to build up along the list
of items.
Also, fix bugs in the collection filtering - previously items
like markers were filtered out only after the selection size
was used to compute the gaps between items.
When editing the board, footprint fields _look_ like text items, so copy
and paste of these items should logically result in a text item, not a
footprint copy.

(And we already filter all mandatory fields in
pasteFootprintItemsToFootprintEditor() anyway.)
Also, don't nuke a footprint which contains only fields
during a paste.

Circles only use one dimension and we tend to ignore the other in our UI
but it is kept and reflects the previous second dimensional value. When
checking DRC, we should only be concerned with the single value used
unless the pad has two dimensions

Zoom-to-selection should only show the elements that we can see, so
avoiding hidden fields in footprints keeps the zoom window appropriately
sized
Fixes https://gitlab.com/kicad/code/kicad/-/issues/15245
We used to have special cases to keep fields from bloating
a footprint's bounding box or being used for hit-testing.
However, now that we can distinguish PCB_FIELD_T from
PCB_TEXT_T, we should not apply these special cases to
PCB_TEXT_T. Text in footprints should act like graphics.
