Some users might want to specify simple files (such as pre-built tools)
in the target attribute of native_tool_toolchain.

Fixes cross-compiling from macos to linux.
see #997 for background.
I had to make a couple of extra changes to support this:
Setting CMAKE_SYSTEM_NAME manually causes CMAKE_SYSTEM_PROCESSOR to not be set. This breaks some builds that expect this variable to be set like libjpeg-turbo.
I made it so that the above variables are only set when cross-compilation is detected so that rules_foreign_cc only takes on responsibility of setting them when necessary.
* 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
