This makes it easier to reason about our packages.
The only difference is what each package downloads.
When the browser is not downloaded, it will fail to launch.
Each browser gets a 'download' attribute in the browser.json file.
Currently, Ctrl-C while extracting browser might yield users in
a bad place.
This patch adds a marker file inside browser directory to make
sure that browser extraction completed.
Note: this was already attempted in #2489, but was eventually
reverted in #2534.

We now commit protocol.ts files during the roll.
New utils/roll_browser.js helps with that.
This makes our installation very shallow:
- build installer;
- download browsers.
This reverts 2 commits:
- "fix(installer): create tmp directory inside `browserPath` (#2498)"
commit 946b4efa3b.
- "feat: support atomic installation of browsers (#2489)"
commit 3de0c087bc.
This addresses installation issues we see in some CI environments.
