GH-46147: [C++] Implement GCS support in Meson (#47568)
### Rationale for this change
This continues adding features to the Meson configuration (azure is already
implemented)
### What changes are included in this PR?
System-provided GCS can be leveraged to build optional GCS features. Note
that this does not support Meson to automatically download GCS - GCS is a
rather complicated CMake project and does not work well in the Meson/CMake
subproject bridge. Another PR will have to implement that, due to its
complexity (or ideally a Meson wrap for GCS is created)
### Are these changes tested?
Yes
### Are there any user-facing changes?
No
