Bump MSRV (Minimum Supported Rust Version) to 1.54.0 (#703)

1.51.0 clippy has been giving me trouble (not reporting all problems),
and so I take the easy way out and just bump MSRV.

We will upgrade to 1.56.0 once it comes around anyway
to get access to that sweet disjoint capture in closures
(https://doc.rust-lang.org/nightly/edition-guide/rust-2021/disjoint-capture-in-closures.html)

 * All `Ui`:s must now have a finite `max_rect`.
   * Deprecated: `max_rect_finite`, `available_size_before_wrap_finite` and `available_rect_before_wrap_finite`.
 * `Painter`/`Fonts`: text layout now expect color when creating a `Galley`. You may override that color with `Painter::galley_with_color`.

 ### Fixed 🐛
 * Fix wrongly sized multiline `TextEdit` in justified layouts.
