The linked ARM wiki docs are obsolete, and will soon be unnecessary.
Additionally, the "processor" requirement is entirely redundant since we
support all processors compatible with macOS 10.12 or later.

* Puts the docs in order, so that contributors aren't jumping to the
middle of the page to install system tools, then back to the top to
clone Firefox.
* Removes docs on MacPorts since it's being removed in bug 1688263.
* Removes step to manually install brew packages since that happens
automatically in bootstrap now.
* Simplifies mercurial installation docs
* Removes unnecessary mozconfig-tweaking instructions
* Removes almost-always-unnecessary DEFINE and troubleshooting
information.

This is a requirement anyway, and the bootstrap script will yell at you if it can't find `hg` (or `git`, if it's necessary), but we can be more specific about this requirement here so people don't waste any more time than necessary.

Today the docs tell you to directly clone `mozilla-central`, which is a weird departure from what we do in the other per-platform documents for no real reason. Instead, reference the standalone `bootstrap.py` script as we do for Linux and macOS.
Also, do a little scan and replace references to `mozilla-central` with `mozilla-unified` where appropriate.

`bootstrap` won't be able to install them for you forever (and it isn't really properly capable of installing it for you at this very moment), and installing Python 3 as well as Python 2 is increasingly non-trivial on arbitrary OS'es, so we need to document things properly here.
Specific guidance on how to use `brew` to install Python 2 on macOS is included here. I also go into more depth on the situation on Linux and explicitly point people to the existence of `pyenv` with basic usage information, which should fill in the gaps left by the OS package managers.
Also, update some documentation to prefer the `python3` binary to the `python` binary (which is often Python 2), and fix some broken links.
