Update port gstreamer
- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- [x] SHA512s are updated for each updated download.
- [ ] The "supports" clause reflects platforms that may be fixed by this
new version.
- [ ] Any fixed [CI
baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt)
entries are removed from that file.
- [ ] Any patches that are no longer applied are deleted from the port's
directory.
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is added to each modified port's versions file.
Add port libsoup,libpsl,glib-networking
- [x] Changes comply with the [maintainer
guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md).
- [x] The name of the port matches an existing name for this component
on https://repology.org/ if possible, and/or is strongly associated with
that component on search engines.
- [x] Optional dependencies are resolved in exactly one way. For
example, if the component is built with CMake, all `find_package` calls
are REQUIRED, are satisfied by `vcpkg.json`'s declared dependencies, or
disabled with
[CMAKE_DISABLE_FIND_PACKAGE_Xxx](https://cmake.org/cmake/help/latest/variable/CMAKE_DISABLE_FIND_PACKAGE_PackageName.html).
- [x] The versioning scheme in `vcpkg.json` matches what upstream says.
- [x] The license declaration in `vcpkg.json` matches what upstream
says.
- [x] The installed as the "copyright" file matches what upstream says.
- [x] The source code of the component installed comes from an
authoritative source.
- [x] The generated "usage text" is accurate. See
[adding-usage](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/examples/adding-usage.md)
for context.
- [x] The version database is fixed by rerunning `./vcpkg x-add-version
--all` and committing the result.
- [x] Only one version is in the new port's versions file.
- [x] Only one version is added to each modified port's versions file.
I found the offical tutorials not work because the uridecodebin plugin
can not handle https uri. Then I found that soup plugins is disabled. So
I update the gstreamer to enable it. The gstreamer compiled successfuly
without new port which I add. However the soup plugins will not work
without libsoup. So I add the port libsoup. And it depend on libpsl and
glib-networking. The glib-networking is a gio module. To make it work,
we should set env GIO_MODULE_DIR to the plugins dir which
glib-networking dll live in. And now I uridecodebin works properly.
By the way, how vcpkg deal with plugin dll? I put them to a plugins dir
just like gstreamer. However to use them is a hard work. For a gio
module, we have to set the env GIO_MODULE_DIR to the dyamic library
location.
