feat(ext/node): eagerly bootstrap node (#20153)

To fix bugs around detection of when node emulation is required, we will
just eagerly initialize it. The improvements we make to reduce the
impact of the startup time:

 - [x] Process stdin/stdout/stderr are lazily created
 - [x] node.js global proxy no longer allocates on each access check
- [x] Process checks for `beforeExit` listeners before doing expensive
shutdown work
- [x] Process should avoid adding global event handlers until listeners
are added
