1) Move a bunch of std::map's to std::unordered_map to get constant-time
look-ups
2) Lengthen progress-reporting intervals to spend more time doing work
and less time talking about it
3) Reverse order of SHAPE_LINE_CHAINs in thermal intersection checks to
make (much) better use of bbox caches
4) Don't re-generate bboxes we already have
5) Fix some autos that weren't by reference (and were therefore copying
large datasets)
6) Rename delta progressDelta so it's easier to search for in future
7) Get rid of a few more autos (because I don't like them)
8) Pass large items to lambdas by reference

Threaded DRC access will write to this string, re-allocating the memory
without any synchronization between threads using the string. Comment
adding this listed performance as a reason for using shared strings.
Measured performance does not seem noticeably different in either case,
even with high-error count boards. If there is a case where the
performance is limiting, we can replace these wxStrings with
std::wstring and utilize fmt

The main issue was a parameter mismatch which caused On^2 behaviour
for zone layers.
But there are several other performance optimizations here, along
with status bar updating for zones while running the dissallow test.

1) Don't report on tests not run.
2) Don't cancel subsequent tests because the current test didn't
have any constraints
3) Exit a little bit quicker when cancelled

Push DRC zone RTrees into BOARD so that they can also be used by
insideArea.
All these caches are a bit of an encapsulation leak, but they make a
significant impact on performance.
Fixes https://gitlab.com/kicad/code/kicad/issues/7720
Also fixes a bug in silk-to-mask checking which wasn't checking
zones on the mask layer.
Also a perfomance fix for the DRC RTree to use a hash table (std::map)
instead of a std::set for keeping track of known collisions.
