docs: Update macOS development docs with dispatch.h error solution (#11986)
### Title
Update macOS Development Documentation with Dispatch.h Error Solution

### Description
This PR updates the macOS development documentation to include a
solution for the `dispatch/dispatch.h` file not found error. This error
is encountered during local development when using the `cargo run`
command. The documentation now includes steps to ensure the Xcode
command line tools are properly installed and set, and instructions to
set the `BINDGEN_EXTRA_CLANG_ARGS` environment variable.

### Changes
- Added troubleshooting section for `dispatch/dispatch.h` error in
`development/macos.md`.

### Related Issues
- Closes [#11963](https://github.com/zed-industries/zed/issues/11963)

### Testing Instructions
1. Follow the steps in the updated `development/macos.md` to configure
your environment.
2. Run `cargo clean` and `cargo run` to ensure the build completes
successfully.

# Building Zed for macOS
## Repository
Clone down the [Zed repository](https://github.com/zed-industries/zed).
## Dependencies
- Install [Rust](https://www.rust-lang.org/tools/install)
- Install [Xcode](https://apps.apple.com/us/app/xcode/id497799835?mt=12) from the macOS App Store, or from the [Apple Developer](https://developer.apple.com/download/all/) website. Note this requires a developer account.
> Ensure you launch XCode after installing, and install the MacOS components, which is the default option.
- Install [Xcode command line tools](https://developer.apple.com/xcode/resources/)
```bash
xcode-select --install
```
- Ensure that the Xcode command line tools are using your newly installed copy of Xcode:
```
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
```
* Install the Rust wasm toolchain:
```bash
rustup target add wasm32-wasi
```
## Backend Dependencies
If you are developing collaborative features of Zed, you'll need to install the dependencies of zed's `collab` server:
- Install [Postgres](https://postgresapp.com)
- Install [Livekit](https://formulae.brew.sh/formula/livekit) and [Foreman](https://formulae.brew.sh/formula/foreman)
```bash
brew install livekit foreman
```
Alternatively, if you have [Docker](https://www.docker.com/) installed you can bring up all the `collab` dependencies using Docker Compose:
```sh
docker compose up -d
```
## Building Zed from Source
Once you have the dependencies installed, you can build Zed using [Cargo](https://doc.rust-lang.org/cargo/).
For a debug build:
```
cargo run
```
For a release build:
```
cargo run --release
```
And to run the tests:
```
cargo test --workspace
```
## Troubleshooting
### Error compiling metal shaders
```
error: failed to run custom build command for gpui v0.1.0 (/Users/path/to/zed)`**
xcrun: error: unable to find utility "metal", not a developer tool or in PATH
```
Try `sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer`
### Cargo errors claiming that a dependency is using unstable features
Try `cargo clean` and `cargo build`.
### Error: 'dispatch/dispatch.h' file not found
If you encounter an error similar to:
```bash
src/platform/mac/dispatch.h:1:10: fatal error: 'dispatch/dispatch.h' file not found
Caused by:
process didn't exit successfully
--- stdout
cargo:rustc-link-lib=framework=System
cargo:rerun-if-changed=src/platform/mac/dispatch.h
cargo:rerun-if-env-changed=TARGET
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS_aarch64-apple-darwin
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS_aarch64_apple_darwin
cargo:rerun-if-env-changed=BINDGEN_EXTRA_CLANG_ARGS
```
This file is part of Xcode. Ensure you have installed the Xcode command line tools and set the correct path:
```bash
xcode-select --install
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
```
Additionally, set the `BINDGEN_EXTRA_CLANG_ARGS` environment variable:
```bash
export BINDGEN_EXTRA_CLANG_ARGS="--sysroot=$(xcrun --show-sdk-path)"
```
Then clean and rebuild the project:
```bash
cargo clean
cargo run
```
