Fix detection of CSS Preprocessor Comments at Start of File in Emmet Extension (#146121)

Browse Source 
* Fix for PartialStyleSheet getting stuck in loop

Adds a clause for detecting `//` as a comment marker when working backwards through a file, preventing the parser from getting stuck when the comment starts at 1:1

* Modify change to detect start of file instead of skipping additional `/` characters now that we know the issue only occurs at offset 0.
