feat(Editor): Add Vim mode

[coder3101]

Vi mode is very popular and is widely used by many programmers. It speeds up so many tasks and so those who are used to it, do not like to code on any other editor. This is stopping many from adapting CP Editor as their main Editor for competitive Programming. This PR adds support for Vi mode in the code Editor using a popular extension written by the authors of Qt Creator called FakeVim.

Motivation and Context

I like to code in Vim too and sometimes I don't like CP Editor because of it not having Vim Support.

How Has This Been Tested?

• Primarily testing and being developed on Arch Linux
• Final testing will include Windows 10

@ouuan Please review the PR or list down the issues, So I can acknowledge them or point if those could be solved.

Some problems:

1. Many shortcuts are not available, including Ctrl+O, Ctrl+P, Ctrl+T, Ctrl+K, etc. Maybe Make most shortcuts customizable #214 helps.
2. Fake Vim doesn't some code editor settings. I suggest moving the Fake Vim settings to the Code Edit section, and add "Fake Vim is not enabled" as a dependency of the unsupported code editor settings:

       "depends": [
           {
               "name": "FakeVim/Enable",
               "check": "return !var.toBool();"
           }
       ],

3. Add Vim Cursor QCodeEditor#28 (comment)
4. When the cursor is at the beginning/end of a line, and moved to a character left/right, the current line highlight disappears.
5. The settings are not well formatted:
