Support Paredit's whole functionalities

[whitphx]

Now only forwardSexp and backwardSexp are covered by this extension, however, paredit.js provides more functionalities and those should be supported.

[kshartman]

does that include killSexp?

An implementation of paredit-kill was added in https://github.com/whitphx/vscode-emacs-mcx/pull/1425. It is very usable, but there are a few bugs to fix still: see https://github.com/whitphx/vscode-emacs-mcx/issues/1914

Referring to: https://github.com/ailisp/strict-paredit-vscode This contains lots of Paredit keybindings.

Why implement these into this extension?

[dandavison]

Thanks @bobslee, I wasn't aware of that project. Do you know how tied to lisp usage they are? For example, I use the paredit-kill implemented here in #1425 in basically all languages to kill to the end of the current expression (for some definition of "expression").

@dandavison I just started using VS Code, so I don't know yet.
