Before this change the error message for `process.loadEnvFile()` without
an `.env` file present in the current working directory was looking like
this: `ENOENT: .env, Failed to load '%s'.` This obviously isn't what the
author intended.
To fix that, just return a "plain" ENOENT open error. It should be
descriptive enough. That means for the above example, the error message
is now `ENOENT: no such file or directory, open '.env'`.

A function tail calls [[noreturn]] node::Abort will print an incorrect
call stack because the frame pc was advanced when calling node::Abort
to an invalid op, which may vary on different platforms.
Dumps the backtrace in the ABORT macro instead to avoid calling
backtrace in a tail [[noreturn]] call. Removes the [[noreturn]]
attribute if a function calls backtrace and may be called as a tail
statement.
[[noreturn]] attribute of public functions like `napi_fatal_error` and
`node::OnFatalError` can not be removed as compilers may complain
about no return values after the removal.

We previously only return startup data for the first slot for
BaseObjects because we can already serialize all the necessary
information in one go, but slots that do not get special startup
data would be serialized verbatim which means that the pointer
addresses are going to be part of the snapshot blob, resulting
in indeterminism.
This patch updates the serialization routines and capture information
for both of the two slots - the first slot with type information
and memory management type (which we can use in the future for
cppgc-managed objects) and the second slot with data about the
object itself. This way the embeedder slots can be serialized
in a reproducible manner in the snapshot.

This patch makes the binding templates ObjectTemplates, since we
don't actually need the constructor function. This also avoids
setting the properties on prototype, and instead initializes them
directly on the object template.
Previously the initialization was similar to:
```
function Binding() {}
Binding.prototype.property = ...;
module.exports = new Binding;
```
Now it's similar to:
```
module.exports = { property: ... };
```

This patch moves the initialization of per-isolate properties of
the bindings that are in the embedded snapshot separate from the
initialization of their per-context properties. This is necessary
for workers to share the isolate snapshot with the main thread
and deserialize these properties instead of creating them from
scratch.

Add an ExitCode enum class and use it throughout the code base
instead of hard-coding the exit codes everywhere. At the moment,
the exit codes used in many places do not actually conform to
what the documentation describes. With the new enums (which
are also available to the JS land as constants in an internal
binding) we could migrate to a more consistent usage of the
codes, and eventually expose the constants to the user land
when they are stable enough.

Instead of iterating over the bindings, iterate over the base
objects that are snapshottable. This allows us to snapshot
base objects that are not bindings. In addition this refactors
the InternalFieldInfo class to eliminate potential undefined
behaviors, and renames it to InternalFieldInfoBase.
The {de}serialize callbacks now expect a InternalFieldInfo struct
nested in Snapshotable classes that can be used to carry
serialization data around. This allows us to create structs
inheriting from InternalFieldInfo for Snapshotable objects
that need custom fields.

This patch updates the layout of the BaseObjects to make sure
that the first embedder field of them is a "type" pointer, the
first 16 bits of which are the Node.js embedder ID, so that
cppgc will always skip over them. In addition we now use this
field to determine if the native object should be interpreted
as a Node.js embedder object in the serialization and deserialization
callbacks for the startup snapshot to improve the reliability.

This is supposed to be a public alternative of the private APIs,
`process._getActiveResources()` and `process._getActiveHandles()`. When
called, it returns an array of strings containing the types of the
active resources that are currently keeping the event loop alive.

Put the hrtime backing store in the process methods binding data
so that it can be integrated into the snapshot builder. For
now we simply discard the contents of the hrtime buffer during
serialization and create new buffers upon deserialization because
the contents are only useful in a synchronous call.
This also moves the helper function for creating V8 FastAPI methods
into `Environment::SetFastMethod()` for code reuse. The v8::CFunction
need to be created before the Environment is created so that we
have the CTypeInfo address available for external reference
registration.
