[meson] Make Meson generate artifacts in the style of #650.

This change refactors where Meson emits its Ninja files to make the
design proposed by imphil in #650 possible. In particular, there are now
two build directories:
- build-out, which has an unstable directory structure, is where Meson
  builds actually occur.
- build-bin, which has a stable directory structure, is where finished
  build outputs are copied by ci/make_build_bin.sh.

util/make_build_bin.sh is a simple script that copies finished build
artifacts out of build-out into build-bin, meant to be invoked during
CI.

util/build_consts.sh contains build directory structure definitions,
which other scripts can source to access build directories in a portable
manner.

A followup change will add scripts to invoke fusesoc to cause top-level
hardware artifacts to be build into build-out and build-bin.

About the project

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the the OpenTitan site and OpenTitan docs for more information about the project.

About this repository

This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.

Documentation

The project contains comprehensive documentation of all IPs and tools. You can either access it online or build it locally by following the steps below.

  1. Ensure that you have the required Python modules installed (to be executed in the repository root):
$ sudo apt install curl python3 python3-pip
$ pip3 install --user -r python-requirements.txt
  1. Execute the build script:
$ ./util/build_docs.py --preview

This compiles the documentation into ./build/docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:1313.
