As due to https://github.com/mesonbuild/meson/issues/9702 we are not
using the expansion of @PACKAGE_INIT@ anyway, the cmake module provides
little additional value over a plain configure_file().
More importantly, by not using it, we get full support for muon, which
does not implement the cmake module yet.
* Remove wrong librz.pc.in file
* Add plugindir variable to .pc files to allow easy plugin configuration
* Add CMake config files to find Rizin in CMake projects
* Add CI jobs to check cmake files
* Provide workaround for mesonbuild/meson#9702
* Use .lib suffix and no prefix on MSVC to make CMake files work
* Disable cmake files on static libraries build
