Eric Huss 797112ef36 Clean up some fs-related utilities
This does a little cleanup around the usage of filesystem functions:

- Add `mdbook_core::utils::fs::read_to_string` as a wrapper around
  `std::fs::read_to_string` to provide better error messages. Use
  this wherever a file is read.
- Add `mdbook_core::utils::fs::create_dir_all` as a wrapper around
  `std::fs::create_dir_all` to provide better error messages. Use
  this wherever a file is read.
- Replace `mdbook_core::utils::fs::write_file` with `write` to mirror
  the `std::fs::write` API.
- Remove `mdbook_core::utils::fs::create_file`. It was generally not
  used anymore.
- Scrub the usage of `std::fs` to use the new wrappers. This doesn't
  remove it 100%, but it is now significantly reduced.
