Migrate project data from setup.py -> pyproject.toml

Preperation for using setuptools-git-versioning which will require a [project]
entry in pyproject.toml. Once that exists many keywords in setup.py would need
to be declared as dynamic in pyproject.toml. Since they're in practice static
I elected to bite the bullet and migrate everything.

An example error

```
********************************************************************************
The following seems to be defined outside of `pyproject.toml`:

`description = 'A WebAssembly runtime powered by Wasmtime'`

According to the spec (see the link below), however, setuptools CANNOT
consider this value unless `description` is listed as `dynamic`.

https://packaging.python.org/en/latest/specifications/pyproject-toml/#declaring-project-metadata-the-project-table

To prevent this problem, you can list `description` under `dynamic` or alternatively
remove the `[project]` table from your file and rely entirely on other means of
configuration.
