This pull request introduces a new `markdown` crate which is capable of
parsing and rendering a Markdown source. One of the key additions is
that it enables text selection within a `Markdown` view. Eventually,
this will replace `RichText` but for now the goal is to use it in the
assistant revamped assistant in the spirit of making progress.

Note that this pull request doesn't yet use the new markdown renderer in
`assistant2`. This is because we need to modify the assistant before
slotting in the new renderer and I wanted to merge this independently of
those changes.

Note: You shouldn't use the `unstable.ui_density` setting – it is only
being added for testing and to enable new UI components to be built with
density in mind. Don't expect this to work well, or at all right now.
Adds some of the basic wiring we'll need to start scaling UI elements
throughout the app based on a desired density setting.

This PR adds a new `rems_from_px` helper function that can be used to
compute rem values based on a pixel value.
This is something we do fairly commonly, where we want to express a size
that is a given pixel size at the base rem size (e.g., "14px when the
rem size is 16px").
`rems_from_px` helps make the intent more explicit, as well as prevent
the base rem size from being duplicated everywhere.
Note: Ideally we would want `rems_from_px` to be `const`, but that
depends on https://github.com/rust-lang/rust/issues/57241.

This PR cleans up a number of references in doc comments in the `ui` and
`theme` crates so that `rustdoc` will link and display them correctly.
