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.

Locally the hashing of the binding names sometimes has significant
presence in the profile of bindings, because there can be collisions,
which makes the cost of adding a new binding data non-trivial,
but it's wasteful to spend time on hashing them or dealing with
collisions at all, since we can just use the EmbedderObjectType
enum as the key, as the string names are not actually used beyond
debugging purposes and can be easily matched with a macro.
And since we can just use the enum as the key, we do not even
need the map and can just use an array with the enum as indices
for the lookup.

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.

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.

Instead of passing them through the data bound to function
templates, store references to them in a list embedded inside
the context.
This makes the function templates more context-independent,
and makes it possible to embed binding data in non-main contexts.

Inline `ProcessCliArgs()` in the `Environment` constructor, and
emit the `Environment` creation trace events with the arguments
earlier. Remove the unused arguments passed to `CreateProcessObject()`
since these are now attached to process in `PatchProcessObject()`
during pre-execution instead.

Previously, we call the JS land `runNextTicks` implementation
immediately from JS land after evaluating the main module or the
input, so these synchronous JS call frames would show up in the stack
trace of the async errors, which can be confusing. This patch moves
those calls into C++ so that more of these internal scheduler
implementation details can be hidden and the users can see a cleaner
a cleaner async JS stack trace.

Use a `v8::Object` with an internal field, rather than a
`v8::External`.
On a `GetReturnValue().Set(Environment::GetCurrent(args) == nullptr)`
noop function, this benchmarks as a ~60 % speedup, as calls to
`obj->GetAlignedPointerFromInternalField()` can be inlined and
the field is stored with one level of indirection less.
This also makes breaking up some pieces of the `Environment` class
into per-native-binding data easier, if we want to pursue that path
in the future.
