* Add a undo/redo split test case for crossing branches

* history: Switch up/down transaction chaining order

The old code tends to work in practice because, usually, either up_txns
or down_txns are empty. When both have contents though, we can run into
a panic trying to compose them all since they will disagree on the
length of the text. This fixes the panic test case in the parent
commit.
provideFormatter enables capability in LS and
auto-format performs format on save

Add highlight scopes for golang built-in functions and types.
Based on https://pkg.go.dev/builtin.
* Change default TS object bindings

Changes 'match inside/around' bindings for:
- type definition from `c` to `t`
- comments from `o` to `c`
- tests from `t` to `T`

Also changes those for the `]` / `[` bindings.

* Update docs for changed keybinds

Completion edits - either basic `insert_text` strings or structured
`text_edit`s - are assumed by the LSP spec to apply to the current
cursor (or at least the trigger point). We can use the range (if any)
and text given by the Language Server to create a transaction that
changes all ranges in the current selection though, allowing auto-
complete to affect multiple cursors.

* rework positioning/rendering, enables softwrap/virtual text

This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.

A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

The purpose of this change is to remove the mutable self borrow on
`HighlightIterLayer::sort_key` so that we can sort layers with the
correct ordering using the `Vec::sort` function family.
`HighlightIterLayer::sort_key` needs `&mut self` since it calls
`Peekable::peek` which needs `&mut self`. `Vec::sort` functions
only give immutable borrows of the elements to ensure the
correctness of the sort.

We could instead approach this by creating an eager Peekable and using
that instead of `std::iter::Peekable` to wrap `QueryCaptures`:

```rust
struct EagerPeekable<I: Iterator> {
    iter: I,
    peeked: Option<I::Item>,
}

impl<I: Iterator> EagerPeekable<I> {
    fn new(mut iter: I) -> Self {
        let peeked = iter.next();
        Self { iter, peeked }
    }

    fn peek(&self) -> Option<&I::Item> {
        self.peeked.as_ref()
    }
}

impl<I: Iterator> Iterator for EagerPeekable<I> {
    type Item = I::Item;

    fn next(&mut self) -> Option<Self::Item> {
        std::mem::replace(&mut self.peeked, self.iter.next())
    }
}
```

This would be a cleaner approach (notice how `EagerPeekable::peek`
takes `&self` rather than `&mut self`), however this doesn't work in
practice because the Items emitted by the `tree_sitter::QueryCaptures`
Iterator must be consumed before the next Item is returned.
`Iterator::next` on `tree_sitter::QueryCaptures` modifies the
`QueryMatch` returned by the last call of `next`. This behavior is
not currently reflected in the lifetimes/structure of `QueryCaptures`.

This fixes an issue with layers being out of order when using combined
injections since the old code only checked the first range in the
layer. Layers being out of order could cause missing highlights for
combined-injections content.
This change makes `ms<ret>` work similarly to `t<ret>` and related
find commands: when the next event is a keypress of Enter, surround
the selection with the document's line-endings.
If the last argument to shellwords ends in a multibyte utf8 character
the entire argument will be dropped.
e.g. `:sh echo test1 test2𒀀` will only output `test1`

Add additional tests based on the code review feedback
* hide duplicate symlinks from the picker

* Apply suggestions from code review

After discussing it further, it's best to have it done every time, a
couple options can be explored to reduce false positives in the future.
