Implement bootstrap-gstreamer for all platforms

Browse source 
This change makes it so that the Platform classes can now handle
installing GStreamer dependencies and properly setting up the
environment including when cross-compiling. For Windows and Linux
is now installed into `target/dependencies/gstreamer` when not installed
system-wide. In addition:

1. Creating and moving existing environment path append helpers to
   `util.py`.
2. Combining the `set_run_env` and `build_dev` functions and moving
   some outside code into them so that it can be shared. Now code that
   used to call `set_run_env` calls `build_dev` and then
   `os.environ.update(...)`.
3. Adding Python typing information in many places.

#### macOS
Xcode version 10.2 or above is recommended.

NOTE: run these steps after you've cloned the project locally.
``` sh
cd servo
bash etc/install_macos_gstreamer.sh
brew bundle install --file=etc/homebrew/Brewfile
pip install virtualenv
```
- Install Xcode (version 10.2 or above is recommended)
- Run `./mach bootstrap-gstreamer`. This will install the recommended version of GStreamer globally on your system.
- Run `brew bundle install --file=etc/homebrew/Brewfile`
- Run `pip install virtualenv`

Additionally, you'll need a local copy of GStreamer with a version later than 16.2. You can place it in `support/linux/gstreamer/gst`, or run `./mach bootstrap-gstreamer` to set it up. On **Ubuntu 20.04LTS**, you can use the system GStreamer if you install the necessary packages:
``` sh
sudo apt install gstreamer1.0-nice gstreamer1.0-plugins-bad
```
You will also need GStreamer which you can install in two ways:
1. On **Ubuntu 20.04 LTS or greater**: The system version of GStreamer is sufficient if you install the necessary plugins:
```
sudo apt install gstreamer1.0-nice gstreamer1.0-plugins-bad
```
2. Run `./mach bootstrap-gstreamer` to install the prepackaged binaries into the `target` directory.
If you are using **Ubuntu 16.04** or **Linux Mint 18**, run `export HARFBUZZ_SYS_NO_PKG_CONFIG=1` before building to avoid an error with harfbuzz.

1. Install Python 3.9 for Windows (https://www.python.org/downloads/release/python-392/). The Windows x86-64 MSI installer is fine. This is required in order to build the JavaScript engine, SpiderMonkey.
You will also need to set the `PYTHON3` environment variable, e.g., to 'C:\Python39\python.exe' by doing:
```
setx PYTHON3 "C:\Python39\python.exe" /m
```
The `/m` will set it system-wide for all future command windows.

If this does not work, you may need to reboot for the changed PATH settings (by the python installer) to take effect.

3. Install GStreamer:
```
mach bootstrap-gstreamer

You can also install GStreamer manually using the MSVC (**not MingGW**) binaries from the [GStreamer](https://gstreamer.freedesktop.org/data/pkg/windows/) site. The currently recommended version is 1.16.0. i.e:
3. Install the most recent [GStreamer](https://gstreamer.freedesktop.org/data/pkg/windows/) MSVC packages. You need to download the two `.msi` files for your platform from the [GStreamer](https://gstreamer.freedesktop.org/data/pkg/windows/) website and install them. The currently recommended version is 1.16.0. i.e.:
- [gstreamer-1.0-msvc-x86_64-1.16.0.msi](https://gstreamer.freedesktop.org/data/pkg/windows/1.16.0/gstreamer-1.0-msvc-x86_64-1.16.0.msi)
- [gstreamer-1.0-devel-msvc-x86_64-1.16.0.msi](https://gstreamer.freedesktop.org/data/pkg/windows/1.16.0/gstreamer-1.0-devel-msvc-x86_64-1.16.0.msi)
- [gstreamer-1.0-msvc-x86_64-1.16.0.msi](https://gstreamer.freedesktop.org/data/pkg/windows/1.16.0/gstreamer-1.0-msvc-x86_64-1.16.0.msi)

Note that the MinGW binaries will not work, so make sure that you install the MSVC ones.
Note that you should ensure that _all_ components are installed from gstreamer, as we require many of the optional libraries that are not installed by default.

4. Install Git for Windows (https://git-scm.com/download/win). DO allow it to add git.exe to the PATH (default
settings for the installer are fine).
5. Install Visual Studio Build Tools 2019 (https://visualstudio.microsoft.com/de/downloads/#build-tools-for-visual-studio-2019). It is easiest to install via [Chocolatey](https://chocolatey.org/install#installing-chocolatey) with:
```
choco install -y visualstudio2019buildtools --package-parameters="--add Microsoft.VisualStudio.Component.Roslyn.Compiler --add Microsoft.Component.MSBuild --add Microsoft.VisualStudio.Component.CoreBuildTools --add Microsoft.VisualStudio.Workload.MSBuildTools --add Microsoft.VisualStudio.Component.Windows10SDK --add Microsoft.VisualStudio.Component.VC.CoreBuildTools --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.VC.Redist.14.Latest --add Microsoft.VisualStudio.Component.VC.ATL --add Microsoft.VisualStudio.Component.VC.ATLMFC --add Microsoft.VisualStudio.Component.TextTemplating --add Microsoft.VisualStudio.Component.VC.CoreIde --add Microsoft.VisualStudio.ComponentGroup.NativeDesktop.Core --add Microsoft.VisualStudio.Workload.VCTools"
```
If you really need to use the Visual Studio Installer (UI), choose "Desktop development with C++" and add the optional "MSVC", "C++-ATL" and "C++-MFC" (latest).
```
