When highlighting the removed parts of a suggestion, properly account for spans that cover more than one line.
Fix #134485.

Passing an explicit boolean value (`on`, `off` etc.) appears to work, but
actually puts the compiler into an unintended state where unstable _options_
are still forbidden, but unstable values of _some_ stable options are allowed.

Add nightly-only theming support to rustc output using Unicode box
drawing characters instead of ASCII-art to draw the terminal UI:
After:
```
error: foo
╭▸ test.rs:3:3
│
3 │ X0 Y0 Z0
│ ┌───╿──│──┘
│ ┌│───│──┘
│ ┏││━━━┙
│ ┃││
4 │ ┃││ X1 Y1 Z1
5 │ ┃││ X2 Y2 Z2
│ ┃│└────╿──│──┘ `Z` label
│ ┃└─────│──┤
│ ┗━━━━━━┥ `Y` is a good letter too
│ `X` is a good letter
╰╴
note: bar
╭▸ test.rs:4:3
│
4 │ ┏ X1 Y1 Z1
5 │ ┃ X2 Y2 Z2
6 │ ┃ X3 Y3 Z3
│ ┗━━━━━━━━━━┛
├ note: bar
╰ note: baz

╭▸ test.rs:4:3

```
Before:

beta was branched long ago, so can be removed

|
Leverage `anstyle-svg`, as `cargo` does now, to emit `.svg` files
instead of `.stderr` files for tests that explicitly enable color
output. This will make reviewing changes to the graphical output of
tests much more human friendly.

this is kinda jank because it means people need both machines to bless the tests
|
|
according to a poll of gay people in my phone, purple is the most popular color to use for highlighting
| color | percentage |
| ---------- | ---------- |
| bold white | 6% |
| blue | 14% |
| cyan | 26% |
| purple | 37% |
| magenta | 17% |
unfortunately, purple is not supported by 16-color terminals, which rustc apparently wants to support for some reason.
until we require support for full 256-color terms (e.g. by doing the same feature detection as we currently do for urls), we can't use it.
instead, i have collapsed the purple votes into magenta on the theory that they're close, and also because magenta is pretty.
