Tig 4c6145cee9 Fixes #4233 - CharMap rendering (#4255)
* Fixed almost all issues

* code comments

* fixed copilot suggestion

* Add Unicode filtering and improve context menu handling

Enabled nullable reference types for better null safety. Added a
Unicode category filter to `CharacterMap` via the new
`ShowUnicodeCategory` property and `OptionSelector`. Updated
rendering logic to dynamically manage visible rows based on the
filter, improving performance and usability.

Refactored menu items to include the Unicode category selector.
Enhanced `TextView` context menu handling to support mouse-based
positioning. Performed miscellaneous code cleanup and added
comments for improved readability and maintainability.

* Fix Unicode rendering and simplify CombiningMarks

Updated `RuneExtensions.GetColumns` to handle specific Unicode glyphs (I Ching symbols) rendered as double-width in Windows Terminal, despite being single-width per Unicode. Added a workaround to return `2` for these glyphs and fallback to `UnicodeCalculator.GetWidth` for others.

Simplified `CombiningMarks` by removing examples for Unicode characters `\u0600` and `\u0301`, streamlining the scenario.

Referenced PR #4255 for context on the workaround.

* Update RuneTests with new Unicode test cases and fixes

Added new test cases for Unicode characters U+d7b0 (ힰ) and
U+f61e () with expected parameters. Updated the test case
for U+4dc0 (䷀) to adjust the second parameter from 1 to 2
and added references to the Microsoft Terminal Unicode
width overrides file and GitHub issue #19389. Existing test
cases for other Unicode characters remain unchanged.

* Update Terminal.Gui/Views/CharMap/CharMap.cs

* Update comments in GetColumns method for clarity

Updated comments in the `GetColumns` method of the `RuneExtensions` class to replace "HACK" with "TODO" and reference issue #4259 instead of pull request #4255. This change clarifies that the code is a temporary measure and should be removed once the issue is resolved. No functional changes were made to the code logic.

Terminal.Gui Tests

This folder contains the tests for Terminal.Gui.

./UnitTests

This folder contains the unit tests for Terminal.Gui that can not be run in parallel. This is because they depend on Application or other class that use static state or ConfigurationManager.

We should be striving to move as many tests as possible to the ./UnitTestsParallelizable folder.

./UnitTestsParallelizable

This folder contains the unit tests for Terminal.Gui that can be run in parallel.

./IntegrationTests

This folder contains the integration tests for Terminal.Gui.

./StressTests

This folder contains the stress tests for Terminal.Gui.

./PerformanceTests

This folder WILL contain the performance tests for Terminal.Gui.

See the Testing wiki for details on how to add more tests.
