Build rules for interfacing with "foreign" (non-Bazel) build systems (CMake, configure-make, GNU Make, boost, ninja, Meson)

* Add meson support * Modify zlib to be detected via pkgconfig in dependent rules * Modify zlib and expat to be linked to shared libs in dependent rules * Add example usage of Meson rule This commit adds the glib library to the "examples" build. glib requires pcre2, so pcre and libgit2 (a dependent of pcre) have been updated/modified * Add example usage of meson_with_requirements macro This commit adds mesa to the "examples" build. This commit also changes the "examples" build to use the hermetic python toolchain provided by rules_foreign_cc. As such, the python toolchain built by rules_foreign_cc is no longer used, as it cannot be used in workspace rules, .e.g pip_parse(). As such, the python2 build has been removed from the examples as python2 is end-of-life. Until Bazel 4.2.0, the built-in android toolchain required Python 2. As such the minimum supported version has been upversioned to 4.2.0. Note that the BAZEL_VC env var was removed from CI as mesa requires MSVC 2019. * Set visibility for each target in foreign_cc_rule_variant * Apply formatting changes * Get meson examples working with bzlmod Note that a newer version of pkgconfig than that installed in ubuntu 20 must be used to build libxau, therefore the built_pkgconfig_toolchain is now registered |

rules_foreign_cc
Rules for building C/C++ projects using foreign build systems inside Bazel projects.
This is not an officially supported Google product (meaning, support and/or new releases may be limited.)
Documentation
Documentation for all rules and providers are available at: https://bazelbuild.github.io/rules_foreign_cc/
Bazel versions compatibility
Works with Bazel after 4.2.0.
The following flags are required in Bazel 4.x but not Bazel 5.x or newer:
--experimental_enable_aggregating_middleman=False
Note that the rules may be compatible with older versions of Bazel but support may break in future changes as these older versions are not tested.

Caveats
- FreeBSD support is currently experimental and on a best-effort basis. Google currently doesn't have a CI test environment for FreeBSD, but please make your voice heard by upvoting this issue.
