meson is a build system focused on speed an ease of use, which
helps speeding up the software development. This patch adds meson
support along autotools.
The template files in the `build-aux` directory used in enums sources
and headers generation use the `{$name}-template.[ch]` pattern.
However, the examples in the official guide[0] and usually GNOME and
Freedesktop packages use the `{$name}.[ch].template` pattern.
Due to this, the name of the template files and build commands have
been changed.

mm-enums-types.c: In function ‘mm_modem_lock_get_string’:
mm-enums-types.c:165:17: warning: comparison of integer expressions of different signedness: ‘MMModemLock’ {aka ‘enum <anonymous>’} and ‘gint’ {aka ‘const int’} [-Wsign-compare]
165 | if (val == mm_modem_lock_values[i].value)
| ^~
The code to handle the Enums and Flags type information is automatically built
with `glib-mkenums' and the new templates kept under `build-aux'.
Note: We currently skip the type information of `MMModemBand'. GFlagsValue
can hold only 32-bit types, and we're working with a 64-bit flag here.
