### Problem description
This PR implements some rudimentary Xcode support for building and
editing ImHex.
### Implementation description
#### Problem 1: Xcode is a multi-configuration buildsystem
The project is already rather CMake generator independent, thus it did
not need to change much to support Xcode's multi-configuration paradigm:
By default, CMake generates a `.xcodeproj` in which targets build their
artifacts into the specified `<>_OUTPUT_DIRECTORY`, postfixed by the
currently active configuration. To better fit the existing paradigm, I
instead opted ot introduce `IMHEX_MAIN_OUTPUT_DIRECTORY`. This variable
is equal to the previously used `RUNTIME_OUTPUT_DIRECTORY` when using
other generators, and is changed to include a configuration specific
_prefix_ when used with Xcode.
The result is different output directories when using Xcode, and no
changes when using any other generator.
#### Problem 2: ImHex does not support AppleClang
To allow building the codebase with Xcode, I have introduced
`IMHEX_IDE_HELPERS_OVERRIDE_XCODE_COMPILER`. Specifying this option to
`ON` will force CMake to honor the user specified compiler settings,
even when using the Xcode generator.
In practice this can be used together with the new "xcode" CMakePreset
to build the project with mainline clang using `xcodebuild`, or Xcode
itself by generating a buildsystem like so:
```
cmake --preset xcode -DCMAKE_PREFIX_PATH=/opt/homebrew/opt/llvm@17
```
This solution is of course not without flaws. The inner workings are a
particularly ugly hack, and mainline clang does not implement the
necessary extensions to allow Xcode to index the code. Regardless this
option is useful to enable future work in terms of bundling/signing
macOS applications in the "intended" way using Xcode without additional
source modifications.
#### Problem 3: Vanilla CMake + Xcode = Bad developer UX
By default, the CMake generated `.xcodeproj` is a mess. Tons of targets
are scattered about, and source files are not organized beyond grouping
them into a "Source Files" and "Header Files" group.
Even "Header Files" is missing, because the ImHex build system does not
regard private header files of libraries as sources of a target, and
Xcode does not try to guess this information.
The solution is twofold:
* Additional code has been added which organizes the targets into a neat
folder structure
* Additional code was added behind a configuration flag
`IMHEX_IDE_HELPERS_INTRUSIVE_IDE_TWEAKS` which automatically creates
source file trees in Xcode targets, and discovers the non-declared
header files via the folder convention.
### Screenshots
N/A
### Additional things
As a bonus: `IMHEX_OFFLINE_BUILD` assumes that ImHex-Patterns is cloned
into the source tree. I have added an additional fallback that tries to
locate it as a sibling folder of `${CMAKE_SOURCE_DIR}`, as this meshes
better with my filesystem setup.
The setup was tested with `CMake 3.29.2`, `Xcode 15.2`, and `llvm@17`
from homebrew.
### Problem description
https://gitlab.freedesktop.org/mesa/mesa/-/issues/11135
It turns out LLVMpipe only supports 4x multisampling. Checking
GL_MAX_SAMPLES seems like the right thing to do.
### Implementation description
~~Right now, I only check GL_MAX_SAMPLES. Depending on the format, we
might need to check GL_MAX_INTEGER_SAMPLES. I don't know how likely it
is that you might want to use a different format in the future,
glGetInternalformativ might be a safer option to retrieve the max number
of samples we can use.~~
Ended up implementing it with glGetInternalformativ.
### Additional things
I guess I could merge the ```if```s at lines 95, 99 and 103 in
imgui_imhex_extensions.cpp while we're at it.

* dist/fedora: Include file magic headers
Due to differences in package names between Deb based systems, Arch
Linux, and RPM based systems the package containing the development
headers for file were missing from the Fedora dependencies script.
This includes the package `file-devel`, which is the package which
resolves the issue.
In Fedora, one can identify the package providing a specific file using
the verb "whatprovides" with the command dnf, e.g.:
[~]$ dnf whatprovides /usr/include/magic.h

Resolves#48
* dist: Prevent already installed packages in ArchLinux and MSYS2.
Use --needed option with pacman to prevent it.
* Add script to install dependencies on Debian/Ubuntu.
Tested with Xubuntu 20.04 and Debian testing
(in today's Docker image bitnami/minideb).
Update README.md.
* ci: rework (#31)
* Support non standard LLVM library names (#86)
This fix openSUSE and Gentoo issue mentioned in https://github.com/WerWolv/ImHex/issues/37#issuecomment-739503138.
(tested on openSUSE tumbleweed via Docker)
I also took the liberty of renaming llvm_lib to llvm_demangle_lib to be more specific in the ``CMakeLists.txt``.
* Implement proper DPI handling
* Implement basic custom font support
* Fix building on windows
* Hopefully fix fonts on Windows
* Fix several scaling issues
* Replace font renderer with freetype
* Updated CI and dependency scripts
* Rebuild default font atlas
* Correct platform detection macro for mingw
* Fixed PKGBUILD
