### 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

### Problem description
Typing `--help` causes ImHex to exit without outputting anything.
Diagnostic messages from glib, ASan, other libraries that might have
something important to say, etc. are also suppressed.
### Implementation description
This effectively reverts 7c1e33dde6, which
was partially reverted only on Windows by code that was left commented
out in f114239f51.
Allowing other libraries to print to stderr may make the output ‘ugly’,
but lots of things print to stderr that are important for figuring out
why something is bugged, like ASan and glib.
