Also adds some debugging to try to catch dangling pointers.
Also adds a cache for group bounding boxes (which will be expensive
to calculate for large groups).

This function convert a text shape to a set of polygons for the 3D viewer.
Texts shapes are a bit special and can generate a lot of small overlapping polygons.
These polygons are now merged before being added to the list of polygons handled
by the 3D viewer draw functions.
Locally merging polygons is usually not efficient but in this case it can speedup
the 3D viewer (up to 10x).
Mainly noticeable for silkscreen layers when the "copper" thickness is shown
Since EDA_TEXT is a base class, we can just force the child classes to pass the correct iu scaled size
ALLOW_BOLD_THICKNESS removed because it's a pre-custom font holdover
When building the connectivity database, we should not be using the
connectivity to check for shapes.
To make this deterministic, we introduce two flags (ALWAYS_FLASH and
NEVER_FLASH) that are used with connectivity building to determine
whether a pad is flashed for connectivity or not. ZONE <-> PAD/VIA
connectivity will be checked with ALWAYS_FLASHED and all other
connectivity will be checked with NEVER_FLASHED if they are marked for
potential annular ring removal. If they are not marked for removal,
they will be checked ALWAYS_FLASHED.

Also fixes a bug where outline fonts weren't being handled for footprint
text in 3D Viewer, and a copy/paste error in stroke font handling for
both PCB and footprint text in 3D Viewer.

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.
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.
