Since disable network was added cargo configurations which reference git
repos fail as they attempt to fetch across the network as part of
do_compile, even if EXTRA_OECARGO_PATHS to add them as part of `paths`
is used, as this is documented as only working for packages which exist
in crates.io.
Add parsing of the SRC_URIs for git repos and include `[patch]` sections
to redirect to the checked out source repos which the bitbake fetcher
has already populated.
There are still cases which don't work - if you have multiple copies of
the same repo with different revisions, there's currently no way to
represent that and anything using a repo which has a virtual manifest
will fail to build (see https://github.com/rust-lang/cargo/issues/4934).

This is for a specific case where:
- A recipe use a subpath on a git repo (e.g. git://repo.git/projects;subpath=subproject)
- The recipe contains a patch to apply
- a devtool modify is used on this recipe
With these conditions, the patch cannot be applied at all.
GitApplyTree class is used for handling patch under devtool, but
when subpath is present in SRC_URI, the resulting git tree
is dirty (every files and directories which was not in subpath are suppressed)
and so "git am" refuse to apply patches.
That would not be an issue since the GitApplyTree have a fallback
to PatchTree in case of error, but during this error management,
there is a "git reset --hard HEAD" call which suppress the subpath
operation and finally prevents the patch to be applied even with PatchTree.
When devtool is not involved, only PatchTree class is used and the
above problem is irrelevant.
To support git patching during devtool, the presence of subpath and
the dirtyness of the repo are checked. If both conditions are
met, we directly call PatchTree like it was already done
in case of error during git apply.
