cmake: Improve error handling in `cmake -E tar` command

This Merge Request is related to: #16834

With this Merge Request I would like to improve error handling by cmake -E tar, with following steps:

• If archive needs to be created then list of files are mandatory. Otherwise error message will be displayed.
• Update tar documentation with not described arguments.
• During creation of archive, if one file cannot be read, then continue with adding next files. This is a mimic of original tar implementation.
