Add installation and build instructions for Python bindings (#1392)
This commit adds a small section on how to install and build Python
bindings wheels to the docs, as well as a link to it from the main readme.

Notes were added that clearly state availability of Python wheels based
on Python version and OS/architecture combinations.

For the guide to build a wheel from source, the best practice of
creating a virtual environment and activating it before build was
detailed. Also, a note on the required installation of Bazel was added,
with a link to the official docs on installation.

# Building and installing Python bindings
Python bindings are available as wheels on [PyPI](https://pypi.org/project/google-benchmark/) for importing and
using Google Benchmark directly in Python.
Currently, pre-built wheels exist for macOS (both ARM64 and Intel x86), Linux x86-64 and 64-bit Windows.
Supported Python versions are Python 3.7 - 3.10.
To install Google Benchmark's Python bindings, run:
```bash
python -m pip install --upgrade pip # for manylinux2014 support
python -m pip install google-benchmark
```
In order to keep your system Python interpreter clean, it is advisable to run these commands in a virtual
environment. See the [official Python documentation](https://docs.python.org/3/library/venv.html)
on how to create virtual environments.
To build a wheel directly from source, you can follow these steps:
```bash
git clone https://github.com/google/benchmark.git
cd benchmark
# create a virtual environment and activate it
python3 -m venv venv --system-site-packages
source venv/bin/activate # .\venv\Scripts\Activate.ps1 on Windows
# upgrade Python's system-wide packages
python -m pip install --upgrade pip setuptools wheel
# builds the wheel and stores it in the directory "wheelhouse".
python -m pip wheel . -w wheelhouse
```
NB: Building wheels from source requires Bazel. For platform-specific instructions on how to install Bazel,
refer to the [Bazel installation docs](https://bazel.build/install).
