Enable the attribute "console" of custom_target() introduced in meson
0.48. This allows to get a feedback of what gradle does (which can takes
a very long time).
This produces warnings because we declare to support meson >= 0.37, but
we don't want to stop supporting older versions for that. Older versions
just ignore the option:
> WARNING: Unknown keyword arguments in target scrcpy-server: console
Newer meson versions use it, but warn because we declare supporting
older versions:
> WARNING: Project targetting '>= 0.37' but tried to use feature
> introduced in '0.48.0': console arg in custom_target
Meson does not support conditional branches to suppress such warnings,
so just keep the warnings.
