refactor: remove PermissionsContainer in deno_runtime (#24119)
Also removes permissions being passed in for node resolution. It was
completely useless because we only checked it for reading package.json
files, but Deno reading package.json files for resolution is perfectly
fine.

My guess is this is also a perf improvement because Deno is doing less
work.
