docs: Update debugging docs to mention Meson build options

Browse Source 
The behaviour of the Meson build has changed a little vs what we did in
autotools. In autotools, --enable-debug was a tristate (yes, no,
undefined), with all three options resulting in different macro
definitions.

In Meson, we have a bistate of --buildtype={debug,debugoptimized} vs
--buildtype=(anything else). There is no way to automatically define
G_DISABLE_ASSERT or G_DISABLE_CHECKS while building GLib — you need to
define them in your CPPFLAGS in your environment instead.

Such traps lead to immediate code halts to examine the current
