Remove getStaticDirectory()

[Rich-Harris]

Describe the problem

As with #7798, getStaticDirectory() is unused by official adapters. Static assets are included in getClientDirectory(), and the adapter has a list of files in static, so it's not necessary.

It's quite likely that we'll want to support static: ['static', process.env.THEME] or something like that in future, and getStaticDirectory() would make that somewhat tricky.

Describe the proposed solution

Check community adapters aren't using getStaticDirectory(), and remove it.
