Introduce deterministic property execution, built-in generators, shrinking, replayable seeds, and a separate Progmasoft-owned header API while preserving Catch2 compatibility targets and the C++14 engine baseline.

Add Bazel, Meson, Xmake, and Premake integration and tests alongside the existing CMake build. Replace Linux-only workflow coverage with Windows and macOS jobs and document the Catch2/Catch3 distinction.

This PR primarily accomplishes two tasks:

1) It adds MODULE.bazel.lock to the .gitignore file.
2) It includes a Bazel build rule for SelfTest, which can be utilized with the command bazel test //tests:catch2_self_test.

* Removed Conan1 build.py file using conan package tools that are no longer supported

* Working conan 1 and 2 build with the test package. 

updated the test_package to be updated to conan 2 and fixed missing cmake. Still need to check that the license file is packaged up and that the packages look identical before the changes

* Removing debug prints and the license check that isn't working yet

* Working license file copied over as it was before

* Migrated the properties of cpp_info to conan 2. Keeping conan 1 support by checking the version of conan

https://docs.conan.io/1/migrating_to_2.0/properties.html

* Revert "Removed Conan1 build.py file using conan package tools that are no longer supported"

This reverts commit a606d1dfe6e118199be8a371403717e3e42ad5da.

* Need to add a set_version to parse the version from CMakeLists.txt

Adding a package build yaml to ensure conan keeps building on 1 and 2

* Setting lowercase catch2 for pkg_config and cmake_target_name

* Fixing the namespace for conan file cmake_target_name

The Meson[1] build system makes it easier incorporate third-party
libaries into a project if they also build using Meson.

Let's add a minimal Meson build that's compatible with the CMake build,
along with a GitHub workflow to check that it builds and that at least
the simplest SelfTest runs.

The handling of catch_user_config.hpp is inspired by BUILD.bazel and
doesn't attempt to support any configuratons options. Such features
could be added later.

Meson strongly discourages using wildcards to specify sources, so the
source and header lists are copied from CMakeLists.txt.

Add a new test workflow to test the Meson builds. I was unable to get
these tests to pass with Ubuntu 20.04, so they use Ubuntu 22.04.

I'm neither a CMake nor a Meson expert, but the results seem to work for
me.
