The generator does not read Gir.toml from dependencies, missing out on
trait renames like `ObjectExt` turning into GstObjectExt` (to prevent
clashes with `glib`'s `ObjectExt`). Renaming through `trait_name` is
now taken into account in `gir` thanks to [1], but the renames still
need to be availble to all crates referencing this type. Fortunately
only `Gst.Object` is affected - other renamed traits are not extended in
any of the other crates.

Also separate the lower/upper bound in the name with an underscore. This
cannot be added between `Range` and the first number, that's violating
`non_camel_case_types`.
When importing the prelude of a crate like `gst` the `glib` prelude is
provided too. Shedding these imports saves quite a few lines and
adheres to keeping it simple; we're not reexporting base/parent preludes
for no reason :)
For cleanliness the prelude module only needs to reexport preludes from
direct, "top-most" crates, which themselves take care of reexporting
preludes from its dependencies again. This shaves off some code while
maintaining the same set of exports.
This was temporarily allowed by Value trait refactoring, but the root
cause of the unused imports has been found (`glib::ToValue` for property
getters) and fixed in https://github.com/gtk-rs/gir/pull/1117.
In gir it was brought up [1] that some traits (in particular
`*ExtManual`) are exported from the crate root in addition to the
prelude, cluttering the environment unnecessarily. This commit removes
all these reexports, leaving those in prelude (that were already there)
only.
After this commit everything matching `Ext(Manual)?\b` in `lib.rs` sits
within `pub mod prelude {};`.

`generator.py` can now be used to perform documentation generation and
embedding in one go, simplifying the entire process while at the same
time getting rid of intermediate `docs.md` being checked in to the
repository. For this the CI needs the submodules with `gir` and the
`.gir` files.
The generator (the script that invokes `gir` for all `Gir.toml` crates)
is now shared between all projects that utilize `gir` to simplify
collaboration, instead of having to copy-paste improvements back and
forth. All GStreamer-rs specifics (path to `gst-gir-files`) has been
taken care of by using `girs_directories` in `Gir.toml` instead like
`gtk(4)-rs`.
The `lgpl-docs` and documentation embedding step is now solely invoked
from `./gir/generator.py` in the CI, and does not need the embed/purge
build features anymore.
The generator is now solely in charge of the output path. Besides, only
few crates were inconsistently defining this path while the rest was
leaving it up to a default or the path specified on the cmdline.
The `lgpl-docs` crate and all precompiled (easy to get outdated!)
docmentation files are removed in favour of being generated at runtime
by the improved generator, both during local development as well as in
the CI.
The previous commit reinstantiated `girs_dir`, and this commit applies
the rename to `girs_directories` and adds the new/missing
`gst-gir-files` directory where GStreamer-specific `.gir` files live.
This reverts commit 7f9fcb09e2.
`generator.py` is in the process of being moved to a generic place in
the `gir` repository for reuse across crates. This means `-d` cannot be
passed for our GStreamer-specific `gst-gir-files` directory anymore, and
should be configured from `Gir.toml` instead.
