Add secure notifications for WSL

[neiljp]

WSL notifications were removed in 0.5.2. We should aim to add back a secure version.

For reference: ea8321d is the commit that removed notifications on WSL and secured it on Linux & macOS.

@neiljp But, I don't understand the security flaw in WSL notifications. I just tested it myself, and although the notifications work fine, the terminal's display breaks(sort-of), with all the text getting exceedingly small. Is this the reason for removing notifications in WSL or was there some other major security-issue?

PS: There is a feature request for this already filed in WSL's github page here.

The issue is the handling of the necessary quoting, which is/was not clear.
