devops: produce ffmpeg builds on bots (#3820)
This patch moves FFMPEG building to buildbots:
- `ffmpeg-mac.zip` is built on Mac 10.14 machine
- `ffmpeg-win32.zip` and `ffmpeg-win64.zip` are cross-compiled on
  Ubuntu 20.04 machine

All builds across the platforms share the same config:
- the same versions of `ffmpeg` and `libvpx`
- the same build configuration for both `ffmpeg` and `libvpx`

The config could be found in the `//browser_patches/ffmpeg/CONFIG.sh`.

The builds will be then copied manually and committed to the git
repository.

Contributing Browser Patches

Firefox and WebKit have additional patches atop to expose necessary capabilities.

Ideally, all these changes should be upstreamed. For the time being, it is possible to setup a browser checkout and develop from there.

WebKit upstream status

1. Setting up local browser checkout

From the playwright repo, run the following command:

$ ./browser_patches/prepare_checkout.sh firefox <path to checkout>

(you can optionally pass "webkit" for a webkit checkout)

If you don't have a checkout, don't pass a path and one will be created for you in ./browser_patches/firefox/checkout

NOTE: this command downloads GBs of data.

This command will:

  • create a browser_upstream remote in the checkout
  • create a playwright-build branch and apply all playwright-required patches to it.

2. Developing a new change

You want to create a new branch off the playwright-build branch.

Assuming that you're under ./browser_patches/firefox/checkout:

$ git checkout -b my-new-feature playwright-build
$ # develop my feature on the my-new-feature branch ....

3. Exporting your change to playwright repo

Once you're happy with the work you did in the browser-land, you want to export it to the playwright repo.

Assuming that you're in the root of the playwright repo and that your browser checkout has your feature branch checked out:

$ ./browser_patches/export.sh firefox <path to checkout>

This script will:

  • create a new patch and put it to the ./browser_patches/firefox/patches/
  • update the ./browser_patches/firefox/UPSTREAM_CONFIG.sh if necessary
  • bump the ./browser_patches/firefox/BUILD_NUMBER number.

If you omit the path to your checkout, the script will assume one is located at ./browser_patches/firefox/checkout

Send a PR to the Playwright repo to be reviewed.

4. Rolling Playwright to the new browser build

Once the patch has been committed, the build bots will kick in, compile and upload a new browser version to all the platforms. Then you can roll the browser:

$ node utils/roll_browser.js chromium 123456
