Drop compatibility aliases.

[ericsnowcurrently]

(depends on PR #7915)

In #7915 I moved some things (related to fs paths) around. To avoid churn, I added some aliases. Those aliases need to be dropped and the churn incurred.

• simply delete src/client/common/platform/pathUtils.ts
• in src/client/common/types.ts, remove the IPathUtils and IsWindows exports

Hi, I'm stuck since the last weeks with this issue trying to compile and install successfully the extension. I began doing the substitution in launchers but I got some errors once I installed the extension.

Extension activation failed, run the 'Developer: Toggle Developer Tools' command for more information.

I also added the @injectable decorator and the Singleton statement in, I guess, the proper file, but, after compiling and installing the extension it throws in the Python console the following (compiled in webpack development mode to avoid classes renaming):

[ERROR 2022-6-4 9:23:2.116]: extension activation failed [Error: Missing required @inject or @multiInject annotation in: argument 0 in class FileSystemPathUtils.

I'm sure I'm missing something really simple but I don't know what. Thanks in advance
