We no longer need libide vapi, deps, or metadata. So drop all of
this now that our moratorium on Vala code inside of Builder
itself is in place.

Now that we only have an indenter and error regex pipeline
addin we can easily port this to Python3 and drop all of our
usage of Vala.

The gvls plugin will continue to provide IDE features for Vala
but done from out-of-process.

This isn't being used, so just drop it for now.

We really dont want this long term, but see if it makes things build.

This needs to be provided by GVls now, and we are going to aggressively
remove Vala code from Builder.

Adds gvls (Vala language server) support in a new plugin. The intention
is to remove the vala-pack plugin as part of this going forward.

This seems to be requiring the interface specification so that the
PyGObject bindings can wire up the vfunc for the interface.

We might get either type back here (yay for "specifications that change
every few months") and we need to sniff it to decode.

We probably also have to come up with a strategy to handle the children[]
array separately from containerName.

These cannot actually be translated because it requires the use of
g_dpgettext2() to provide the context for the translation. These should
have never been changed to NC_() to begin with. If the context is truly
necessary, translators will need to find an alternate way to provide this
by not using the same translation for every msgid using the same wording.

This still isn't supported by the GJS backend, but it at least fixes
the error associated with GObject Introspection.

This also fixes GDK_KEY_Escape from the replace entry so that
too will release the search/replace context.

Fixes #1099

This looked too wrong on a number of non-Adwaita themes. As
much as I prefer the "this is an editable" styling, I'm
tired of seeing poorly implemented themes look so completely
broken.
