meson: Start using common_cflags
- -Wall removed as implied by warning_level=1
- -std removed as implied by c_std
NOTE: cflag -fvisibility=hidden was removed as it hid some symbols required by GTK docs
/usr/bin/ld: power-profiles-daemon-scan.o: in function `get_object_types':
power-profiles-daemon-scan.c:(.text+0x1a): undefined reference to `ppd_action_get_type'
/usr/bin/ld: power-profiles-daemon-scan.c:(.text+0x33): undefined reference to `ppd_driver_get_type'
/usr/bin/ld: power-profiles-daemon-scan.c:(.text+0x4c): undefined reference to `ppd_profile_get_type'
This matches previous visibility behavior.
