Bump CMake to OCCT 8.0.0 and regenerate the SWIG interface, headers,
and pyi stubs from the OCCT 8.0 install tree. Also adapt the static
support code that does not flow through the generator:

* CMakeLists.txt: target OpenCASCADE 8.0.0.
* CommonIncludes.i: hide DEFINE_STANDARD_RTTI{,EXT}_INLINE so SWIG
  can preprocess NCollection_HArray1.hxx etc.
* ExceptionCatcher.i: Standard_Failure no longer derives from
  Standard_Transient (now std::exception); use ExceptionType() and
  what() in place of DynamicType()->Name() / GetMessageString().
* Visualization.h / Visualization.i: replace `Handle_X` deprecated
  typedefs by `Handle(X)` (the deprecated typedefs are gone).
* Display3d.cpp: include <TColStd_IndexedDataMapOfStringString.hxx>
  (no longer pulled in transitively).
* MeshDataSource.cpp: include <Poly_Array1OfTriangle.hxx> (same).

Companion to the wrapper-generator port; generated with the
pythonocc-generator review/occt800 branch + SWIG 4.4.1.

Companion to the wrapper-generator review/occt800 head: regenerate the
SWIG interface files, headers and pyi stubs after the last round of
generator fixes (DEFINE_DERIVED_ATTRIBUTE / DEFINE_STANDARD_RTTI*
detection, NCollection_BaseList shadowing, byref Get/Set shims,
NCollection_HArray1/HArray2/HSequence wraps via typedef pre-pass,
GCE2d_Make* using-aliases, TopExp parameter rewrites, etc).

Also adjust two tests that were written against pre-8.0 semantics:
  - test_core_meshdatasource: NCollection_PackedMap::Statistics() was
    removed in OCCT 8.0; the test only keeps the NbBuckets() check.
  - test_core_wrapper_features::test_shape_analysis_free_bounds:
    ConnectEdgesToWires is now wrapped as a 3-arg function returning
    the resulting wires (the OCCT C++ signature has a 4th
    out-parameter); ShapeAnalysis behaviour around shared vertices
    differs slightly between 7.9 and 8.0.

Result: 189 tests pass, 1 deselected
(test_core_exception.py::test_standard_out_of_range, which segfaults
inside OCCT 8.0rc5's BRepBuilderAPI_Sewing::FreeEdge(-1) rather than
throwing).

Updates the bundled generator.log to match the regenerated SWIG bindings
on the review/occt800 branch (companion to 5716c8e).
