Draft: meson: Add installation tags to installed files

This hasn't been tested since Meson v0.60.0 has not been released at the time of creating this MR.

Installation tags[0] are a feature introduced in Meson v0.60.0 allowing to install only a selected subset of the installable files.

All tags have been assigned in a way that mirrors the file structure. For example the 'file-bmp' plugin has a tag 'plug-ins-file-bmp'.

This raises the required version of Meson to >=0.60.0.
