glib: several fixes & improvements

[SpaceIm]

• fix PkgConfigDeps
• bump dependencies
• relocatable shared libs on macOS (install_name set to @rpath)
• properly rename lib names for compiler=msvc as well
• no need to define libdir in MesonToolchain since min conan version is 1.52.0
• add tests for CMakeDeps & PkgConfigDeps
• use basic_layout (for consistency among CCI recipes)

---

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the conan-center hook activated.

Issue in PkgConfigDeps of test_package coming from libffi recipe. See conan-io/conan#11867. it's something making conan v2 migration tedious.

Waiting layout addition in #13355 & #13445

[SSE4]

I can't see it used anywhere... why is it needed?

[SpaceIm]

Because there are build requirements. My understanding is that it's implicit in conan v2 mode, but not in conan v1 mode by default.
