Allow removing "Upload Local Profile" option from the top bar

I'm trying to use Firefox Profiler in an VS Code extension to open Android profiles from inside VS Code. I'm also planning to extend this to support more supported formats in future.

I was wondering if we should have a way to remove profile uploads and docs link from the top bar.

While the profile upload feature is super useful, in this context it might not make much sense since the paradigm here is essentially opening a profile trace file inside an editor. I wouldn't expect additional ways to upload specific kind of files from inside VS Code. (Also not sure how we think about uploading non-Firefox profiles to this service, but that is separate).
