When clipboard data was produced by the editor's copy/cut with multiple
entire-line selections, vim's paste would panic with `byte index N is
out of bounds`.
The editor's `do_copy` and `cut_common` skip the `\n` separator between
clipboard selections when the previous selection was an entire-line
selection (because the text already ends with `\n`). However, vim's
paste code unconditionally did `start_offset = end_offset + 1`, always
assuming a `\n` separator exists between every pair of selections. This
caused the accumulated offset to exceed the text length, resulting in a
string slicing panic.
The fix checks `clipboard_selection.is_entire_line` to decide whether to
skip the separator, matching the behavior of the editor's own `do_paste`
method. The same fix is applied to both the vim and helix paste
implementations.
Release Notes:
- Fixed a crash when using vim paste on clipboard data copied with the
editor's copy command containing multiple entire-line selections.
Replaces a bunch of `impl FnMut` parameters with `&mut dyn FnMut` for
functions where this is the sole generic parameter.

This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

Re-applies https://github.com/zed-industries/zed/pull/30840
This PR re-applies the initial
[PR](https://github.com/zed-industries/zed/pull/30840). As it was closed
because it was hard to land, because of the many conflicts. This PR
re-applies the changes for it.
In several cases we were creating multiple display_map
snapshots within the same root-level function call.
Creating a display_map snapshot is quite slow, and in some
cases we were creating the snapshot multiple times.

This improves the "C" and "alt-C" actions to work like helix.
It also adds "," which removes all but the newest cursors. In helix the
one that's left would be the primary selection, but I don't think that
has an equivalent yet, so this simulates what would be the primary
selection if it was never cycled with "(" ")".
Release Notes:
- Improved multicursor creation and deletion in helix mode

We have unnecessary clones for the fields here as most of the snapshots
contain the others hierarchically.

I noticed that after we paste in line mode, the cursor position is
positioned at the beginning of the next logical line which is somewhat
undesirable since then inserting/appending will position the cursor
after the selection. This does not match helix behaviour which we should
further investigate.
Follow-up to https://github.com/zed-industries/zed/pull/38663
Release Notes:
- N/A
In particular,
* if the selection ends at the beginning of the next line, and the
current line under the cursor is empty, we paste at the selection's end.
* if however the current line under the cursor is empty, we need to move
to the beginning of the next line to avoid pasting above the end of
current selection
In addition, in line mode, we always move the cursor to the end of the
inserted text. Otherwise, while it looks fine visually,
inserting/appending ends up in the next logical line which is not
desirable.

This is a redo of #29776. I went for a separate function -- instead of
adding a bunch of conditions to `vim::Paste` -- because there were quite
a few differences.
Release Notes:
- Added a `vim::HelixPaste` command that imitates Helix's paste behavior

This is an implementation of matching like "m i (", as well as "] (" and
"[ (" in `helix_mode` with a few supported objects and a basis for more.
Release Notes:
- Added helix operators for selecting text objects
