add a cross platform clip command to the standard library (#8695)
Should close the associated poin in #8311

# Description
this PR adds a `clip` command to `std` which
- has error support in case the clipboard system command is not
installed
- removes any ANSI escape sequences from the input to have a clean
copied text
- can throw desktop notifications on linux in case of a long pipeline
which needs to be copied (can be disabled with `--no-notify`)
- echoes the copied data to the output of the terminal (can be disabled
with --silent)
- has examples and dependencies listed
- has "charpage" 65001 (a.k.a. utf-8) support for windows
