Fix tests (#10906)

Browse Source 
* Get libslic3r tests closer to passing

I can't get geometry tests to do anything useful. I've added extra
output, but it hasn't helped me figure out why they don't work
yet. That's also probably the last broken 3mf test doesn't work.

The config tests were mostly broken because of config name changes.

The placeholder_parser tests have some things that may-or-may-not
still apply to Orca.

* Vendor a 3.x version of Catch2

Everything is surely broken at this point.

* Allow building tests separately from Orca with build_linux.sh

* Remove unnecessary log message screwing up ctest

Same solution as Prusaslicer

* Make 2 TriangleMesh methods const

Since they can be.

* Move method comment to the header where it belongsc

* Add indirectly-included header directly

Transform3d IIRC

* libslic3r tests converted to Catch2 v3

Still has 3 failing tests, but builds and runs.

* Disable 2D convex hull test and comment what I've learned

Not sure the best way to solve this yet.

* Add diff compare method for DynamicConfig

Help the unit test report errors better.

* Perl no longer used, remove comment line

* Clang-format Config.?pp

So difficult to work with ATM

* Remove cpp17 unit tests

Who gives a shit

* Don't need explicit "example" test

We have lots of tests to serve as examples.

* Leave breadcrumb to enable sla_print tests

* Fix serialization of DynamicConfig

Add comments to test, because these code paths might not be even used
anymore.

* Update run_unit_tests to run all the tests

By the time I'm done with the PR all tests will either excluded by
default or passing, so just do all.

* Update how-to-test now that build_linux.sh builds tests separately

* Update cmake regenerate instructions

Read this online; hopefully works.

* Enable slic3rutils test with Catch2 v3

* Port libnest2d and fff_print to Catch2 v3

They build. Many failing.

* Add slightly more info to Objects not fit on bed exception

* Disable failing fff_print tests from running

They're mostly failing for "objects don't fit on bed" for an
infinite-sized bed. Given infinite bed is probably only used in tests,
it probably was incidentally broken long ago.

* Must checkout tests directory in GH Actions

So we get the test data

* Missed a failing fff_print test

* Disable (most/all) broken libnest2d tests

Trying all, not checking yet though

* Fix Polygon convex/concave detection tests

Document the implementation too. Reorganize the tests to be cleaner.

* Update the test script to run tests in parallel

* Get sla_print tests to build

Probably not passing

* Don't cause full project rebuild when updating test CMakeLists.txts

* Revert "Clang-format Config.?pp"

This reverts commit 771e4c0ad2.

/**
* @brief Filters points in a polygon based on a minimum angle threshold and a convex/concave criterion.
*
* This function iterates through the vertices of the input polygon and selects
* points where the internal angle meets or exceeds the specified \p angle_threshold
* and the point satisfies the condition defined by the \p convex_concave_filter.
*
* @tparam ConvexConcaveFilterFn The type of the callable filter object (e.g., function pointer, lambda, functor)
* that determines if a point is considered convex or concave.
* First vector is incoming line segment (ending at point), second vector is leaving current point.
* It should have the signature `bool(const Vec2d&, const Vec2d&)`
* @param poly Vertices of the input polygon.
* @param angle_threshold The **minimum** angle (in radians) that the internal angle at a vertex must meet or exceed. Must be less than Pi (because angle is always positive) and greater than zero.
* @param convex_concave_filter A callable object that returns `true` if the point should be included
* (e.g., if it's convex), and `false` otherwise.
* @return Points Point objects that meet both the angle threshold and the convex/concave filter criterion.
