It turns out that even with startup snapshots, there is a non-trivial
overhead for loading internal modules. This patch makes the loading
of the non-essential modules lazy again.
Caveat: we have to make some of the globals lazily-loaded too,
so the WPT runner is updated to test what the state of the global
scope is after the globals are accessed (and replaced with the
loaded value).

Handle situations in which the main `Promise` from a TLA module
is not fulfilled better:
- When not resolving the `Promise` at all, set a non-zero exit code
(unless another one has been requested explicitly) to distinguish
the result from a successful completion.
- When rejecting the `Promise`, always treat it like an uncaught
exception. In particular, this also ensures a non-zero exit code.

Previously `internal/bootstrap/pre_execution.js` requires
`internal/modules/cjs/loader.js` which in turn requires
`internal/bootstrap/pre_execution.js`. This patch moves the
entry point execution logic out of `pre_execution.js` and
puts it into `internal/modules/run_main.js`. It also tests
that `Module.runMain` can be monkey-patched before further
deprecation/refactoring can be done.
Also added an internal assertion `hasLoadedAnyUserCJSModule`
for documentation purposes.
