Add -W options from Makefile into meson warning_flags

Makefile options were more restrictive and produced more
warnings. This patch adds missing warning options into
meson build.

Makefile also has -Wall and -Wextra specified explicitly,
however this is covered by warning_level=2 which is already
set in meson.build. warning_level info:
https://github.com/mesonbuild/meson/issues/3275

There are few warning options that are present in meson,
but not in Makefile. These are left as is.

TEST=ninja test shows no warnings and tests pass
