The tests for file existence and write status perform two file stats
which cause performance issues on slow network shares. Now the file
state is determined at load time and stored in the SCH_SCREEN object
so file access is no longer required.

When swapping SCH_SYMBOL objects during undo, no special processing is
required. The SCH_PIN objects are updated when the LIB_SYMBOL objects
are swapped and the call to SCH_SCREEN::SwapSymbolLinks() didn't do
anything.
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.

Differentiates better between the EDA_ITEM IsModified(), referring to
items themselves changing and the EDA_SCREEN IsContentModified(),
referring to whether we have made any unsaved changes.
This fix required sorting all of the LIB_PART draw items to ensure
accurate comparison between the symbols stored in the schematic and the
original library symbols. This has a noticeable impact on symbol library
load performance. It may also cause significant changes the next time
the library is saved due to changes in the draw item sorting. Hashing
may be a better solution here but this addressed the immediate problem.
A skeleton method SCH_SCREEN::SwapSymbolLinks() was added because there
is most likely an issue with orphaned symbols in the schematic library
symbol cache during undo/redo operations. More testing is required to
verify this.

Junctions should only be wire endings when ending directly on the wire.
This is the requirement for netlisting, so we need to follow it in the
auto-end as well.
SCH_LABEL needs to allow ending because any wire that touches the label
will be connected, so there's a use case for this. However, the
bounding box for local labels did not include their connection point, so
we increase that box a bit. Note that this might have the opposite
effect to https://gitlab.com/kicad/code/kicad/-/issues/7689

This also makes sure that the user gets a warning before saving over
an older s-expr format. While that won't always be wanted, it's now
in the infobar (like in PCBNew), so it's not too onerous.§

The variable `m_Initialized` in `BASE_SCREEN` is used by
`SCH_EDIT_FRAME` to mark whether a screen had its zoom level initialized
by the "zoom to fit screen" action. When this variable is `false`, the
function `SCH_EDIT_FRAME::DisplayCurrentSheet()` performs "zoom to fit
screen", modifying the zoom level. This function is indirectly called in
the undo routines, so if `m_Initialized` is not set to `true`, a zoom
change will occur when the user undoes an operation, a behavior that is
undesired.
`m_Initialized` was not initialized to `true` for the null schematic
(the schematic that is loaded if no project is loaded), causing the
aforementioned undesired behavior.
To prevent this, I've changed the `SCH_EDIT_FRAME` constructor to set
`m_Initialized` to `true`, since it zooms to fit screen already. I've
moved `m_Initialized` from `BASE_SCREEN` to `SCH_SCREEN`, as it is used
only in Eeschema, and renamed it to `m_zoomInitialized`, a name I
believe that better describes what this variable does.
I've also introduced the function `SCH_EDIT_FRAME::initScreenZoom()` to
group the "zoom to fit screen" action with setting `m_Initialized` to
`true`, as they often should occur together.
I'd also like to say that I'm not confident whether
`SCH_EDIT_FRAME::DisplayCurrentSheet()` should perform the zoom level
initialization at this point, but I have decided to not change this
behavior for now, as the commit history suggests it's several years old.
