Posix vs Win client #182
Description
Hello.
I'm working on the DAP for PHP (https://github.com/xdebug/vscode-php-debug/) and while testing an unusual setup scenario I came to a problem that I'm not sure how to properly solve.
It's regarding path format in the Source type part of StackTraceReqeust and others.
The setup that I had - this is because I did some debugging - was my IDE (neovim) was running in WSL (posix), the debuggee (php) was also running in WSL (posix) but the DAP was running on Win32 (within a VSCode debug session).
The problem that I faced was the code of DAP manipulates paths using https://www.npmjs.com/package/path that by default uses path format depending on the platform it runs on. I can also explicitly tell the library to either use posix or win32 format but the DAP has, as far as I can tell, no idea what platform the client (IDE) is running on.
I understand this is a veeeery specific corner case and probably irrelevant in real life, but I wanted to see if somebody else thinks this should somehow be covered either by a field in InitializeRequestArguments.
Thank you!

After searching around bit more I found some related issues (microsoft/vscode-debugadapter-node#3) and the
pathFormatandDebugSession.setDebuggerPathFormatbut none of those seem to solve this on the protocol level. Question remains, how does the DAP know if the IDE is running POSIX or WIN32.fix: clarify expectations around source.path format

Thanks for the issue, I opened #581 to try to clarify it. Please let me know what you think!
