Improve macOS and Linux build instructions 

- Use CMake's `-B` option to automatically create the build folder
  and avoid the `cd` requirement.
- Use CMake's build tool-agnostic `--build` option to use the same
  build command regardless of whether GNU Make or Ninja is used.
  `--parallel` also ensures that all CPU threads are used by default.
- Mention optional dependency on Ninja for macOS (it's confirmed to work
  there, installed from Homebrew).
- Update Qt macOS path to use the default installation path on a modern
  Homebrew installation. The old path is still mentioned just in case.
- Mention that the generated macOS application bundle may have to be
  manually resigned before it can be run.

The macOS build steps were successfully followed on a 2020 Mac mini
(Apple M1).

### Windows
Requirements:
- Visual Studio 2019
1. Clone the respository with submodules (`git clone --recursive https://github.com/stenzek/duckstation.git -b dev`).
2. Open the Visual Studio solution `duckstation.sln` in the root, or "Open Folder" for cmake build.
3. Build solution.

1. Clone the repository. Submodules aren't necessary, there is only one and it is only used for Windows (`git clone https://github.com/stenzek/duckstation.git -b dev`).
2. Create a build directory, either in-tree or elsewhere.
3. Run cmake to configure the build system. Assuming a build subdirectory of `build-release`, `cd build-release && cmake -DCMAKE_BUILD_TYPE=Release -GNinja ..`.
4. Compile the source code. For the example above, run `ninja`.
3. Run CMake to configure the build system. Assuming a build subdirectory of `build-release`, run `cmake -Bbuild-release -DCMAKE_BUILD_TYPE=Release`. If you have installed Ninja, add `-GNinja` at the end of the CMake command line for faster builds.
4. Compile the source code. For the example above, run `cmake --build build-release --parallel`.
5. Run the binary, located in the build directory under `bin/duckstation-qt`.
### macOS
**NOTE:** macOS is highly experimental and not tested by the developer. Use at your own risk, things may be horribly broken.
**NOTE:** macOS is highly experimental and not tested by the developer. Use at your own risk; things may be horribly broken. Vulkan support may be unstable, so sticking to OpenGL or software renderer is recommended.
Requirements:
- CMake (installed by default? otherwise, `brew install cmake`)
Requirements (can be installed with [Homebrew](https://brew.sh/)):
- CMake (installed by default? Otherwise, run `brew install cmake`)
- SDL2 (`brew install sdl2`)
- Qt 5 (`brew install qt5`)
1. Clone the repository. Submodules aren't necessary, there is only one and it is only used for Windows (`git clone https://github.com/stenzek/duckstation.git -b dev`).
2. Clone the mac externals repository (for MoltenVK): `git clone https://github.com/stenzek/duckstation-ext-mac.git dep/mac`.
2. Create a build directory, either in-tree or elsewhere, e.g. `mkdir build-release`, `cd build-release`.
3. Run cmake to configure the build system: `cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_NOGUI_FRONTEND=OFF -DBUILD_QT_FRONTEND=ON -DUSE_SDL2=ON -DQt5_DIR=/usr/local/opt/qt@5/lib/cmake/Qt5 ..`. You may need to tweak `Qt5_DIR` depending on your system.
4. Compile the source code: `make`. Use `make -jN` where `N` is the number of CPU cores in your system for a faster build.
5. Run the binary, located in the build directory under `bin/DuckStation.app`.
Optional (recommended for faster builds):
- Ninja (`brew install ninja`)
1. Clone the repository. Submodules aren't necessary; there is only one and it is only used for Windows (`git clone https://github.com/stenzek/duckstation.git -b dev`).
2. Clone the macOS externals repository (for MoltenVK): `git clone https://github.com/stenzek/duckstation-ext-mac.git dep/mac`.
3. Run CMake to configure the build system: `cmake -Bbuild-release -DCMAKE_BUILD_TYPE=Release -DBUILD_NOGUI_FRONTEND=OFF -DBUILD_QT_FRONTEND=ON -DUSE_SDL2=ON -DQt5_DIR=/opt/homebrew/opt/qt@5/lib/cmake/Qt5` depending on your system. If you have installed Ninja, add `-GNinja` at the end of the CMake command line for faster builds. Depending on your system, the `Qt5_DIR` value may have to be different (e.g. `/usr/local/opt/qt@5/lib/cmake/Qt5`).
4. Compile the source code: `cmake --build build-release --parallel`.
5. Run the binary, located in the build directory under `bin/DuckStation.app`. If the app crashes on startup, resign it using [macOS Gatekeeper Helper](https://github.com/wynioux/macOS-GateKeeper-Helper).
