Choco: Add support to Extract tar files

[naveen521kk]

This is a request to add a helper function for extracting a tar.xz or a tar.gz files directly.

Currently, the function Get-ChocolateyUnzip but it isn't very helpful, as it first extracts it to .tar and then, it needs to call the same function again, so that, it is extracted. The function Get-ChocolateyUnzip should be handling this instead of making the user call the same function twice.

Cheers.
