xtask: add html-docs task

This task is a bit annoying to implement because `sphinx-build` depends
on `fish_indent`, so that needs to be built, and the binary location
added to `PATH`.

Building `fish_indent` can be avoided by setting the `--fish-indent`
argument to the path to an existing `fish_indent` executable.

Use the new xtask in CMake builds. To do so without having to add
configuration options about where to put the docs, or having to copy
them from the default location to `build/user_doc`, we instead get rid of
the `user_doc` directory and change the code which accesses the docs to
read them from the non-configurable default output location in Cargo's
target directory.
