The actions tracked in the web IDE are:
- creation of commits
- creation of merge requests
- projects loaded

Previously `start_sha` was intercepted on the frontend to create the
correct branch in a separate API call. Now that the commits API supports
the `start_sha` parameter directly this workaround is not needed
anymore.

If an entry has been removed from the tree and later, during the same
session, a user is trying to add a new item with the same name/path we
should allow for that as long as the original entry is marked with
`deleted`.

Update window's URL after entry's re-name

Set proper hook for correct fileLanguage

Filtered out `moved` entries from the tree

**Why?**
The branch HEAD could be changed since the
IDE was opened. This leads to user's unintentionally
creating commits that overwrite other changes.

**Why?**
These values will be used to help build the mirroring diff.
It is helpful keeping it controlled in a constant.

- When uploading a file, we need to flag binary files correspondingly
so that it gets propagated all the way to RepoEditor as it decides on
whether to show editor for this or that file or not (shouldHideEditor())

- rawPath needs to be propagate all the way to ContentViewer as well so
that uploaded images could be rendered as a base64 image right away
instead of raw base64 string

Since we can create files from URL now, this means that these files will
not exist in the tree returned from API: they exist on the client
only before the first commit. In order to still show the newly-created
files in the tree, we should not override the tree, but merge the tree
existing on the client and the one coming from API.

Changelog entry

Moved trees merging into mutation

**How?**
Previously the files_decorator inserted parent folders inefficiently.
It started at the first part and ensured each was inserted.

Since the file entries are given to use in alphabetical order, we can
start at the last part of the blob's parents. If this exists, we can
short circuit and be done inserting parents.

**What else?**
- Improve performance of decorateData. The object spread operator is
not needed because the object is brand new.

fixed folder deletions not adding to changedFiles

for folders, it shows all the files in commit mode
for files, nothing changes, the behaviour is the same

not working for folders yet

Closes #46192

reduced code duplication

the state now gets updated whenever a file is changed/discard

Closes #44838
