meson: rename options file

Meson supports the options being in a `meson.options` instead of a
generic text file so leverage this option. Use of `meson.options`
requires at least meson v1.1.0, but that in turn yields an issue with
the options file:

```
meson.options:2: WARNING: Project targets '>=1.1.0' but uses feature deprecated since '1.1.0': "boolean option" keyword argument "value" of type str. use a boolean, not a string
```

Fix all of these issues together.
