The prompt was previously assuming that each grapheme cluster in the
line was single-width and single-byte. Lines like the one in the new
integration test would cause panics because the anchor attempted to
slice into a character.
This change rewrites the anchor and truncation code in the prompt to
account for Unicode segmentation and width. Now multi-width graphemes
can be hidden by multiple consecutive elipses - for example "十" is
hidden by "……" (2-width).

This completes auto pair deletions. Currently, auto pairs only get
deleted when the range is a single grapheme wide, since otherwise,
the selection would get computed incorrectly through the normal change
mapping process. Now auto pairs get deleted even with larger ranges, and
the resulting selection is correct.
On Windows for example the behavior of this function typically diverges
from the usual behavior on Unix. Instead of checking that the inserted
string starts with `'\n'` (untrue for for CRLF line endings) we need to
check that the first grapheme cluster in the string is a line ending.
(All line endings are single grapheme clusters.)
This matches the behavior described by the EditorConfig spec for its
`insert_final_newline` option:
> Editors must not insert newlines in empty files when saving those
> files, even if `insert_final_newline = true`.

These match the equivalent options in VSCode. `trim_trailing_whitespace`
is also the name used by EditorConfig.
* `trim-final-newlines` trims any extra line endings after the final one
* `trim-trailing-whitespace` trims any trailing whitespace (but not
empty lines)
* fix: panic when pressing `*` at the end of the file
chore: remove incorrect additions
* docs: add info comment
* test: add new syntax to add a selection at the final character
* test: `*` panics when after the last char
* test: move into a more appopriate module
* test: fix failing
* test: account for Windows test suite
* test: choose a different strategy for custom syntax
* test: do not modify the syntax
* style: remove newline

#12177 changed `insert_newline`'s behavior to trim any trailing
whitespace on a line which came before a cursor. `insert_newline` would
previously never delete text. Even the whitespace stripping behavior in
#4854 worked by inserting text - a line ending at the beginning of the
line. `global_offs`, a variable that tracks the number of characters
inserted between iterations over the existing selection ranges, was not
updated to also account for text deleted by the trimming behavior,
causing cursors to be offset by the amount of trailing space deleted
and causing panics in some cases.
To fix this we need to subtract the number of trimmed whitespace
characters from `global_offs`. `global_offs` must become an `isize`
(was a `usize`) because it may become negative in cases where a lot of
trailing whitespace is trimmed. Integration tests have been added for
each of these cases.

* don't use backup files with hardlinks
* check if the inodes remain the same in the test
* move funcs to faccess and use AsRawHandle
* use a copy as a backup for hardlinks
* delete backup after copy
* Remove special-casing of line ending characters in selection replacement
* Refactor line ending handling and integration test to address code review comments
Prior to this change, every integration test which wanted its line
endings to be handled transparently across platforms, i.e. test with
the same input that has its platform's line feed characters, converting
the line endings was up to each individual test by calling the
`platform_line` helper function. This significantly increases the amount
of boilerplate one has to copy between all the tests.
However, there are some test cases that need to exert strict control
over the exact input text without being manipulated behind the scenes by
the test framework.
So, with this change, the line feed conversions are factored into
the `TestCase` struct. By default, line endings of the input text
are converted to the platform's native line feed ending, but one can
explicitly specify in their test case when the input text should be left
alone and tested as is.
This uses the new TreeCursor type from the parent commit to reimplement
the tree-sitter motions (`A-p/o/i/n`). Other tree-sitter related
features like textobjects are not touched with this change and will
need a different, unrelated approach to solve.

Steps To Reproduce
------------------
1. 2j # move_visual_line_down
1. C # copy_selection_on_next_line
1. mdm # surround_delete
Debug
-----
`assertion failed: last <= from', transaction.rs:597:13`
Release
-------
`called `Result::unwrap()` on an `Err` value: Char range out of bounds:
char range 18446744073709551614..18446744073709551615,
Rope/RopeSlice char length 7', ropey-1.6.1/src/rope.rs:546:37`
Description
-----------
Processing the surrounding pairs in order violates the assertion the
ranges are ordered. To handle nested surrounds all positions have to
be sorted. Also surround_replace has to track the proper replacement
character for each position.
1. Create a document containing `{A}`
1. C-w v # vsplit
1. gl # goto_line_end
1. b # move_prev_word_start
1. ` # switch_to_lowercase
1. mrm( # surround replace
1. C-w v # vsplit
In the debug build surround_replace/delete will immedately assert with
`assertion failed: last <= from', transaction.rs:597:13`. The splits and
lowercase conversion are not needed to trigger the bug.
In the release build the surround becomes `)a(` and the last vsplit
causes the transaction to panic.
`internal error: entered unreachable code:
(Some(Retain(18446744073709551573)))', transaction.rs:185:46`
Since the selection direction is backwards get_surround_pos returns the
pairs reversed but the downstream code assumes they are in the forward
direction.
