When working in high contrast mode, we want to be able to select a
footprint with only elements in, e.g. silk and fab layers.
The previous design for footprint IsOnLayer had one behavior of every
other element and a different behavior for footprints. This leads to
multiple bugs as new features use the overloaded IsOnLayer expecting it
to report if the element exists on a layer or not.
For footprints, we need a different routine to determine whether or not
to select the footprint when clicking on it. IsOnLayer will report if
the footprint has any elements on a specific layer but we don't want to
use the bbox for a hittest because large footprints with through hole
pads will exist on every layer and have an enormous bbox. Instead, we
filter footprints based on the hittest of each element. This behaves in
a more logical fashion, allowing you to select a footprint by clicking
on a visible element of that footprint.

Before, we did not actually prevent users from adding a field also named
Quantity to their symbols. This of course does not play nicely with the
assumptions that Quantity is a special column in the fields editor.
By making it a named variable, the user can safely add it to a symbol
and it will not be editable, and will also work in the fields table
editor as expected.
set in undefined, that create an issue (the canonical name was returned as
"Field-1", breaking the schematic file).
Now, new field IDs are not set to -1, and the saved file uses the field name
(if exist) when saving fields with undefined ID.
This needs the ITEM_MODIFICATION_ROUTINE to learn to delete items.
Condense the item change handlers into a single injected object
(ITEM_MODIFICATION_ROUTINE::CHANGE_HANDLER) and provide the basic
implementation that just takes some callables.
This simplifies the construction of the routines and also would make
a CHANGE_HANDLER object possible that can be reused between different
tools.
In the EDIT_TOOL::ModifyLines method, there was some
remaining special-casing for FP childen commits.
One bit was put back by mistake (in
0b32ae3f4b) because I thought I'd
left it out of the refactor. In fact it was removed slightly later in
1218f61d0a.
THe other bit is omitting Modify commits in the FP-editor (what the
reinstatement of the above code was trying to cause). This shouldn't
be needed any more.
However, something is still incomplete here as the tools still don't
work correctly in the footprint editor. However, I don't think it's
substantially _more_ broken with the special casing removed and at
least it's less confusing.

We were calculating the same thing in three locations and we missed
adding the clearance from the footprints in, resulting in bad fills and
missed drc errors (see QA addition)
