This PR changes Node.js/npm compatibility layer to use polyfills for
built-in Node.js
embedded in the snapshot (that are coming from "ext/node" extension).
As a result loading `std/node`, either from
"https://deno.land/std@<latest>/" or
from "DENO_NODE_COMPAT_URL" env variable were removed. All code that is
imported via "npm:" specifiers now uses code embedded in the snapshot.
Several fixes were applied to various modules in "ext/node" to make
tests pass.

This commit changes "ProcState" to store "file_fetcher" field in an "Arc",
allowing it to be preserved between restarts and thus keeping the state
alive between the restarts. File watchers for "deno test" and "deno bench"
now reset "ProcState" between restarts.
Turns out we were cloning permissions which after prompting were discarded,
so the state of permissions was never preserved. To handle that we need to store
all permissions behind "Arc<Mutex<>>" (because there are situations where we
need to send them to other thread).
Testing and benching code still uses "Permissions" in most places - it's undesirable
to share the same permission set between various test/bench files - otherwise
granting or revoking permissions in one file would influence behavior of other test
files.
This commit adds a cache for CJS and ESM analysis that is backed by an
SQLite file.
The connection to the DB is lazily created on first use, so shouldn't
have impact on the startup time.
