gpui: Add support for slash pattern fills (`///`) (#23576)

TODO:
- [x] Add BackgroundTag::PatternSlash
- [x] Support metal slash pattern fills
- [x] Support blade slash pattern fills
---

Adds support for a new background type in gpui, `pattern_slash`.

Usage:

```rust
div().size(px(56.0)).bg(pattern_slash(gpui::red()))
```
This will create a 56px square with a red slash pattern fill.

You can run the pattern example with `cargo run -p gpui --example
pattern`:

After talking with @as-cii at length about how we want to support
patterns in gpui, we decided for now we'll simply add a new
BackgroundTag specific to this pattern.

It isn't the best long term plan however – we'll likely want to
introduce the concept of a `Fill` at some point so we can have
`Fill::Solid`, `Fill::Gradient(LinearGradient)`, etc in the future.

The pattern is designed to seamlessly tile vertically for elements of
the same height. For example, for use in editor line backgrounds:
