Jiho Choi d5c04c34f1 vm: fix `produceCachedData` 
Fix segmentation faults when compiling the same code with
`produceCachedData` option. V8 ignores the option when the code is in
its compilation cache and does not return cached data. Added
`cachedDataProduced` property to `v8.Script` to denote whether the
cached data is produced successfully.

Fedor Indutny b4ece1b7ec contextify: use offset/length from Uint8Array 
Do not blindly take data from underlying `ArrayBuffer`, use
`ByteOffset`/`ByteLength` of `Uint8Array` itself.

Additionally, fix tests that weren't actually properly running because
of V8's internal code cache. The code should be different, otherwise the
cached data won't be used at all.

Fix: #4939

Fedor Indutny 96934cbb30 vm: introduce `cachedData`/`produceCachedData` 
Introduce `cachedData`/`produceCachedData` options for `v8.Script`.
Could be used to consume/produce V8's code cache for speeding up
compilation of known code.
