Commit() and GrowTo() iterate allocating pages, and call RewindPages()
if an iteration fails. This is true even if the first iteration fails,
in which case there are no pages to rewind, and RewindPages() DCHECKs.
Only call RewindPages() if we are on the second or later iteration.

Previously, we sent a critical low memory pressure notification when
attempting to commit WASM code when the code manager was near the
limit for total amount of code allocated.
https://chromium-review.googlesource.com/c/v8/v8/+/1073412 "fixed" that,
but it causes OOMs on Windows.
Since we no longer have the isolate on the code manager, and thus cannot
send this notification on commit, send the notification upon the next
module creation.
This is still not optimal, but should fix OOM issues for lots of
small modules on Windows.

The {WasmSharedModuleData} struct was introduced to hold data common to
all wasm instances belonging to the same module. The idea was to keep
"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

We assumed that if the ErrorThrower is empty after instantiation, then
instantiation succeeded and an instance exists which we can return.
However, if the start function throws, no instance exists, which caused
