[vm/compiler] Forward the ByteData constructor length argument.

In addition, if a _ByteDataView came from a use of the ByteData
constructor, its offset is always 0.

Also add appropriate canonicalization for the following instructions for
typed data views coming from a known factory call:

* LoadField getting type arguments
* GuardFieldLength

This closes https://github.com/dart-lang/sdk/issues/36570.
