### Problem description
This PR addresses issue #2013 that described a cluttered Event Manager.
This is a DX issue and should not impact the users whatsoever.
### Implementation description
The changes revolve around three main points:
1. the Event Manager (`event_manager.hpp`) was split into four
categories: GUI, Interaction, Lifecycle, and Provider, and two types:
Events, and Requests. This results in the following files:
- `events_gui.hpp`
- `events_interaction.hpp`
- `events_lifecycle.hpp`
- `events_provider.hpp`
- `requests_gui.hpp`
- `requests_interaction.hpp`
- `requests_lifecycle.hpp`
- `requests_provider.hpp`
2. Every event and request now has its own piece of documentation, with
a `@brief`, accompanied by a longer comment if needed, and gets its
`@param`s described.
3. The old `event_manager.hpp` import was removed and replaced by the
correct imports wherever needed, as to reduce spread of those files only
to where they are truly useful.
### Additional things
The commits have been split into (chrono-)logical steps:
- `feat`: split the Event Manager, and replace the imports
- `refactor`, `chore`: make various small changes to match the required
structure
- `docs`: add documentation for events and requests
Hopefully, this will help to review the PR.
*Note: Beware of very long rebuild times in between the commits, use
them sparingly! The Actions will ensure this PR builds anyways*
Closes#2013

Fix crash on UNDO/REDO shortcut press when in "title screen"
### Problem description
ImHex crashes when (by default CTRL + Z/Y) undo/redo is pressed when on
"title"/"starting" screen (no file open, tested on Windows release build
and Linux [WSL] from-source build).
This is due to the shortcut's callback being called even if the
`provider` is `nullptr`. (see `createEditMenu` function).
Theoretically, this is prevented by the `enabledCallback` function
passsed to `addMenuItem`. In this case, though,
`addMenuItem` correctly propagates `enabledCallback` to menu item
creation but does not pass `enabledCallback` to
shortcut creation. Thus, when handling shortcuts, `enabledCallback` is
not used at all and the shortcut's callback
can be called in contradiction with its preconditions. (specified by
`enabledCallback`)
### Implementation description
The implementation wraps the callback in a check that decides whether
the shortcut is enabled or not.
(see changed files)
```c++
auto callbackIfEnabled = [enabledCallback, function]{ if (enabledCallback()) { function(); } };
```
This function is then passed along instead of the `function` (shortcut's
callback).
Alternatively, we can check for `nullptr` in the callback directly. This
would require modification of `createEditMenu`'s contents.
(I did not choose this implementation because I do not think it
addresses the root of the issue).
### Screenshots
None
### Additional things
I'm not sure how big of a deal it is but I am unsure whether I can
capture (`[enabledCallback, function]`) by reference or not.
### Problem description
Loading a file on the command line or using the context menu in windows
was triggering an achievement before the achievements file was loaded.
This resulted on the achievements.json file to be overwritten with all
the achievements reset except for the one to open files.
### Implementation description
This PR fixes the problem by introducing a boolean that is used to check
if the file has been loaded.
