#1009, #566: Use clang-format as the default sketch formatter.

[kittaakos]

Motivation

Use clang-format as the default sketch file formatter. It's faster and does not require a running LS.

Change description

• Bumped clangd to 14.0.0,

Other information

Closes #1009
Closes #566

For the reviewers:

• Please open dev tools for verification. Formatting $URI [Range: $RANGE] should be logged when the clang-format-ter is used instead of the LS.
• The formatter should work if the LS is not running.
  

(👆 The Format Document and Format Selection context menu items are available, although the LS is not running.)

• The formatter should work even if there is a whitespace in the sketch name (sketch with spaces.ino) or in the IDE path (/path/to/segment with spaces/arduino-ide).
• Make sure the beginning and the end of the document are formatted (this should verify the correctness of document range calculation).
• It should be possible to add a custom .clang-format file. The precedence is the following:
  • current sketch,
  • ~/.arduinoIDE/.clang-format,
  • directories#data/.clang-format, or
  • falls back to default formatter styles.
• It should be possible to select multiple ranges, not only the entire document:

format.mp4

Reviewer checklist

works well but in this build I still have double tabs per file and full path added (see screenshot)
