feat(permission): separate PermissionDeniedError to Retryable and Fatal (#27282)

Browse source 
This commit separates `PermissionDeniedError` into two kinds;
`Retryable` and `Fatal`.

The existing `PermissionDeniedError`s fall into `Retryable`, since
permission errors can be resolved by retrying with proper permissions in
Deno CLI. The motivation of adding `Fatal` is that in some environments
some operations are just disabled; for instance, in Deno Deploy, any
write operations to filesystem can never be granted, in which case
`Fatal` kind becomes useful.
