Add option in meson to install helper application

Added two new options in meson that allow choosing whether the helper applications (gplugin-gtk-viewer and gplugin-query) are going to be installed or not

Testing Done:
Compiled a few times switching the two new options between true and false and verifying that the behavior was correct.

Bugs closed: GPLUGIN-129

<title>Example Genie Plugin</title>
<para>
Like all plugins in GPlugin, Genie plugins must also implement
the <code>gplugin_query</code>, <code>gplugin_load</code>, and
<code>gplugin_unload</code> functions.
</para>
<para>
Due to the way <code>GPlugin.PluginInfo</code> info works, you must
subclass it and set your values in the new constructor.
</para>
<para>
The following is a basic Genie plugin.
