meson: bump required version to 1.3.0

Newer meson versions added support for features that mpv has been using
for a long time. Annoying fallbacks were left in place to not break old
versions but ideally everyone should be using the newer build features.
Both the latest ubuntu LTS and debian stable (in backports) have 1.5.0
in their repos, so go ahead and bump the version so we can drop some old
code and let developers use newer meson features if applicable.
