Meta: Add .clangd config file (with project-recommended defaults)

Browse source 
This change also removes parts of the existing docs that explain how to
create a .clangd file with the project-recommended  defaults. (Those
docs are no longer necessary — since this change adds a .clangd file to
the repo, containing those same defaults).

# Helix Configuration
Helix comes with support for `clangd` and `clang-format` out of the box! However, a small bit of configuration is needed for it to work correctly with Ladybird.
The following `.clangd` should be placed in the project root:
```yaml
CompileFlags:
CompilationDatabase: Build/ladybird
Diagnostics:
UnusedIncludes: None
MissingIncludes: None
```
You also need to configure the clangd server to not insert headers improperly. To do this, create a `.helix/languages.toml` file in the project root:

The official clangd extension can be used for C++ comprehension. It is recommended in general, as it is most likely to work on all platforms.
clangd uses ``compile_commands.json`` files to understand the project. CMake will generate these in Build/ladybird.
Depending on which configuration you use most, set the CompilationDatabase configuration item in the below ``.clangd`` file accordingly. It goes at the root of your checkout (``ladybird/.clangd``):
```yaml
CompileFlags:
CompilationDatabase: Build/ladybird
Diagnostics:
UnusedIncludes: None
MissingIncludes: None
```
The UnusedIncludes and MissingIncludes flags are used to disable the [Include Cleaner](https://clangd.llvm.org/design/include-cleaner) feature of newer clangd releases.
It can be re-enabled if you don't mind the noisy inlay hints and problems in the problem view.
Run ``./Meta/ladybird.sh run ladybird`` at least once to generate the ``compile_commands.json`` file.
