meson: Disable Python byte-compilation if the Meson version is new enough

Simon McVittierequested to merge
smcv/debhelper:no-bytecode into main

Meson 1.2.0 added support for byte-compilation at build time, and the default is to do so. In Debian we want byte-compilation to be done at package install time, so explicitly turn this off. We cannot pass this option to older Meson versions, because it would make them fail.

Closes: #1042398
