Improve line annotation API
The line annotation as implemented in #5420 had two shortcomings:
* It required the height of virtual text lines to be known ahead time
* It checked for line anchors at every grapheme

The first problem made the API impractical to use in practice because
almost all virtual text needs to be softwrapped. For example inline
diagnostics should be softwrapped to avoid cutting off the diagnostic
message (as no scrolling is possible). While more complex virtual text
like side by side diffs must dynamically calculate the number of empty
lines two align two documents (which requires taking account both
softwrap and virtual text). To address this, the API has been
refactored to use a trait.

The second issue caused some performance overhead and unnecessarily
complicated the `DocumentFormatter`. It was addressed by only calling
the trait mentioned above at line breaks (instead of always). This
allows offers additional flexibility to annotations as it offers
the flexibility to align lines (needed for side by side diffs).

Pascal Kuthe 7cf448eb5b use partition_point instead of binary_search_by
Using `partition_point` ensures we always find the first entry.
With binary search it is "random" (deterministic but implementation
specific) which index is retruned if there are multiple equal elements.
`partition_point` was added to the standard library to cover extactly
the usecase here.

Feat: LSP Type Hints (#5934)
* misc: missing inline, outdated link

* doc: Add new theme keys and config option to book

* fix: don't panic in Tree::try_get(view_id)

Necessary for later, where we could be receiving an LSP response
for a closed window, in which case we don't want to crash while
checking for its existence

* fix: reset idle timer on all mouse events

* refacto: Introduce Overlay::new and InlineAnnotation::new

* refacto: extract make_job_callback from Context::callback

* feat: add LSP display_inlay_hint option to config

* feat: communicate inlay hints support capabilities of helix to LSP server

* feat: Add function to request range of inlay hint from LSP

* feat: Save inlay hints in document, per view

* feat: Update inlay hints on document changes

* feat: Compute inlay hints on idle timeout

* nit: Add todo's about inlay hints for later

* fix: compute text annotations for current view in view.rs, not document.rs

* doc: Improve Document::text_annotations() description

* nit: getters don't use 'get_' in front

* fix: Drop inlay hints annotations on config refresh if necessary

* fix: padding theming for LSP inlay hints

* fix: tracking of outdated inlay hints should not be dependant on document revision (because of undos and such)

* fix: follow LSP spec and don't highlight padding as virtual text

* config: add some LSP inlay hint configs

rework positioning/rendering and enable softwrap/virtual text (#5420)
* 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.
