Tim-Philipp Müller 0a25f22f1b meson: bump meson requirement to >= 0.59
For monorepo build and ugly/bad, for advanced feature
option API like get_option('xyz').required(..) which
we use in combination with the 'gpl' option.

For rest of modules for consistency (people will likely
use newer features based on the top-level requirement).
