fix(view): add props for width and height to x-icon

[iamdadmin]

Closes #1955

• Add props for width and height to x-icon, and ability to disable it entirely so it can be set in style or class

• Add prop for style

• Update docs

• Update tests

Weird, I thought that checks were set for manual trigger, I know they are going to fail as it stands as the tests aren't finished, hence leaving it in draft. Sorry, had I known they'd run I wouldn't have raised it as a draft until I had clean tests!

Ready for review, I'd suggest squashing this commit as prettier which wasn't supposed to run on markdown files, ran on markdown files and really messed up the formatting, so there's some regression commits that are over the top.

Some thoughts I'd like some input on

[iamdadmin]

Since there was a pile of regression commits due to some formatting errors, I rebased, and re-applied the changes to make this a cleaner commit.

Ready for review again, thanks for the feedback!

[brendt]

Can you rebase and resolve the conflicts? Then it's good to merge :)

[iamdadmin]

Awesome, rebased and conflicts resolved :)
