Fix text input cursor setting for multi-line text input with many spaces at the line end

[Districh-ru]

This PR fixes the issue with setting input cursor position when there are many spaces in multi-line text input: #9281 (comment)

Now the multi-line text input field acts like in the original editor - is does not cut spaces at the line end to show user that there are many spaces there and to allow position the cursor at any place of such consequent spaces.

This PR also:

• moves getTextInputCursorPosition() to ui_tool;
• fixes horizontal position of the multi-font text line separated by -

Hi, @ihhub!
I've faced a strange code style check behavior: https://github.com/ihhub/fheroes2/actions/runs/12183834934/job/33986233552?pr=9319
The code was formatted using our .clang-format file.
And also the suggested change (ed15349) looks not good to me.

This formatting is because clang-format treats this as an assignment operation, and there is no knob yet to format assignment operations and pure virtual function declarations in a different way. Please see llvm/llvm-project#57569 for details.

Thanks for clarifying, @oleg-derevenetz!
Visual Studio 2019 has clang-format v.12.0 and uses it even if a newer version installed in the system.
I've updated this clang-format to the latest version (making a symlink to LLVM folder, VS does not look in the PATH environment variable folders) and now formatting goes like Code Style Check wants.

Hi @Districh-ru

I've updated this clang-format to the latest version (making a symlink to LLVM folder, VS does not look in the PATH environment variable folders) and now formatting goes like Code Style Check wants.

There is no need to create symlinks, MSVC can use a custom clang-format executable:
