Fix issue where local terminal failed to open in remote scenarios wsl (#277920)

* try adding options.remoteAuthority field for profile

* try explicit remoteAuthority undefined when local

* Dont touch terminalProfileResolverService.ts

* Better comments to explicitly get local default profile in remote

* Try to handle mac -> linux scenario

* see if caching is problem

* Dont mix up profile and skip list when creating local terminal in remote

* Just handle wsl in this PR to make life simpler

* Logs for debugging

* Allow local to get backend by checking from createTerminal in terminalService.ts

* leave logs to debug, code doesnt work after prev commit

* stringify for better logs. isLocalRemoteTerminal value is still false

* more and more logs

* Bug fixed) Use Schemas.file instead of Shemas.vscodeFileResource
