LibWeb: Properly convert UnderlyingSource's autoAllocateChunkSize to u64

Browse Source 
The JS::Value being passed through is not a bigint, and needs to be
converted using ConvertToInt, as per:

https://webidl.spec.whatwg.org/#es-unsigned-long-long

Furthermore, the IDL definition also specifies that this is associated
with the [EnforceRange] extended attribute.

This makes it actually possible to pass through an autoAllocateChunkSize
to the ReadableStream constructor without it throwing a TypeError.
