Fixes#10926
Contains the following changes:
- Adds a new ERC_SCH_PIN_CONTEXT class which is used to provide deterministic
comparison between items causing ERC violations (e.g. pins) when associated
with a SCH_SHEET_PATH context.
- Adds association of SCH_SHEET_PATHs for ERC_ITEMs and the sub-schematic items
which caused an ERC violation. This allows correct display of markers on the
sheets of interest only, and allows correct naming resolution and cross-probing
from the ERC dialog.
- Adds a new ERC_TREE_MODEL class, derived from RC_TREE_MODEL, which correctly
resolves component references across heirarchical sheets using the associated
SCH_SHEET_PATHs. This allows sheet-specific component references to be displayed
correctly in the ERC results tree.
- Updates SCH_MARKER to only draw sheet-specific markers on the sheet causing
an ERC violation.
- Increments the schematic file version.
- When loading a schematic with legacy ERC exclusions, discards those of type
ERCE_PIN_TO_PIN_WARNING, ERCE_PIN_TO_PIN_ERROR, ERCE_HIERACHICAL_LABEL, and
ERCE_DIFFERENT_UNIT_NET as there is no safe way to automatically infer the
information which is now stored with these exclusions (sheet paths for error
location and related items). Requiring users to (once) re-add exclusions is
preferable to silently incorrectly matching new ERC issues to legacy exclusions.
Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
Also removes EditToolSelectionFilter which was misused in more places
than it was used correctly. The original point of the client filter
was to move the logic to the point of use, which the
EditToolSelectionFilter sort of obviated anyway.

Set up a new lineage for SCH_ITEMS to get back to the SCHEMATIC
they live on: Items will all be parented to the SCH_SCREEN that
they are added to, and each SCH_SCREEN will point back to the
SCHEMATIC that it is part of. Note that this hierarchy is not
the same as the actual schematic hierarchy, which continues to
be managed through SCH_SHEETs and SCH_SHEET_PATHS.
