This PR adds a |preload| arg to the node::LoadEnvironment to allow
embedders to set a preload function for the environment, which will run
after the environment is loaded and before the main script runs.
This is similiar to the --require CLI option, but runs a C++ function,
and can only be set by embedders.
The preload function can be used by embedders to inject scripts before
running the main script, for example:
1. In Electron it is used to initialize the ASAR virtual filesystem,
inject custom process properties, etc.
2. In VS Code it can be used to reset the module search paths for
extensions.

This is similar to the `queryObjects()` console API provided by the
Chromium DevTools console. It can be used to search for objects that
have the matching constructor on its prototype chain in the entire
heap, which can be useful for memory leak regression tests. To avoid
surprising results, users should avoid using this API on constructors
whose implementation they don't control, or on constructors that can
be invoked by other parties in the application.
To avoid accidental leaks, this API does not return raw references to
the objects found. By default, it returns the count of the objects
found. If `options.format` is `'summary'`, it returns an array
containing brief string representations for each object. The visibility
provided in this API is similar to what the heap snapshot provides,
while users can save the cost of serialization and parsing and directly
filer the target objects during the search.
We have been using this API internally for the test suite, which
has been more stable than any other leak regression testing
strategies in the CI. With a public implementation we can now
use the public API instead.

In the SEA tests, if any of these steps fail:
1. Copy the executable
2. Inject the SEA blob
3. Signing the SEA
We skip the test because the error likely comes from the system or
postject and is not something the Node.js core can fix. We only leave
an exception for a basic test that test injecting empty files as
SEA to ensure the workflow is working (but we still skip if copying
fails or signing fails on Windows).

Previously it would not compile if the build is configured with
--disable-single-executable-application because we use directives
to exclude the definition of SEA-related code completely. This patch
changes them so that the SEA code are still compiled and internals
can still check whether the executable is an SEA. The executable would
not try to load the SEA blob at all if SEA is disabled. If future
modifications to the C++ code attempt to load the SEA blob when SEA
is disabled, UNREACHABLE() would be raised. If user attempt to
generate the SEA blob with --experimental-sea-config with an executable
that disables SEA, they would get an error.

New option `--report-exclude-network`, also available as
`report.excludeNetwork`, enables the user to exclude
networking interfaces in their diagnostic report.
On some systems, this can cause the report to take minutes
to generate so this option can be used to optimize that.

Previously the test assumes that when the queued finalizer is run,
it must be run at a point where env->can_call_into_js() is false
(typically, during Environment shutdown), which is not certain.
If GC kicks in early and the second pass finalizer is queued before
the event loop runs the check callbacks, the finalizer would then
be called in check callbacks (via native immediates), where
the finalizer can still call into JS. Essentially, addons can't
make assumptions about where the queued finalizer would be called.
This patch updates the assertions in the test to account for that.

Functions registered with `addSerializeCallback()` can access and call
`process.cwd()`. b7d836e2c7 accounted for the fact that it is
necessary to reset the cwd cache after the snapshot builder script has
run, but did not account for possible accesses from serialization
callbacks. To properly account for these, add a deserialization
callback as well.
As a related drive-by fix, also mention the execution order of
callbacks in the documentation.

In many cases we can query the environment variable directly instead
of encoding it into UTF8 first and then decoding it again from
UTF8 via an intermediate V8 string.
Drive-by: pass per_process::system_environment explicitly when
the real environment variables are supposed to be used instead of
relying on fallback with defaults.
