Refresh the options map during pre-execution to pave the way for
user land snapshots which may need to access run-time options at
snapshot-building time. The default embedded bootstrap snapshot
is still prevented from accessing them at snapshot building time
since it serves a wider audience and is ignorant of application
states, while the user-land snapshots are meant to be
application-specific and so it makes sense for them to access
runtime states as long as the snapshotted-code
works with re-initialized runtime states.

Only query embedder options when they are needed so that the bootstrap
remains as stateless as possible so that the bootstrap snapshot is
controlled solely by configure options, and subsequent runtime changes
should be done in pre-execution.

This change allows all boolean flags to be negated using the `--no-`
prefix.
Flags that are `true` by default (for example `--deprecation`) are
still documented as negations.
With this change, it becomes possible to easily flip the default
value of a boolean flag and to override the value of a flag passed
in the NODE_OPTIONS environment variable.
`process.allowedNodeEnvironmentFlags` contains both the negated and
non-negated versions of boolean flags.

Instead of calling into C++ each time we need to check the value
of a command line option, cache the option map in a new
`internal/options` module for faster access to the values in JS land.
