907dc84c1e LibWeb: Implement min option for ReadableStreamBYOBReader.read()
When the min option is given the read will only be fulfilled when there
are min or more elements available in the readable byte stream.

When the min option is not given the default value for min is 1.

ce521a196d LibWeb: Add non-standard AO set_up_readable_stream
This AO can be used instead of CreateReadableStream in cases where we
need to set up a newly allocated ReadableStream before initialization of
said ReadableStream, i.e. ReadableStream is captured by lambdas in an
uninitialized state.

2a2c59e74b LibWeb: Partially implement the ReadableStream pull-from-bytes AO
We do not handle BYOB request views yet, as they are not needed for the
upcoming usage of this AO.

c29916775e LibWeb: Mark stream AOs as infallible as required by the spec
There were several instances where the spec marks an AO invocation as
infallible, but we were propagating WebIDL::ExceptionOr. These mostly
cannot throw due to knowledge about the values they are provided. By
unwinding these, we can remove a decent amount of exception handling.

These don't throw. We can remove a decent amount of exception handling

bbe6b84bd6 LibWeb: Mark most stream callbacks as infallible
There are a number of script-provided stream callbacks for various
stream operations, such as `start`, `pull`, `cancel`, etc. Out of all of
these, only the `start` callback can actually throw. And when it does,
the exception is realized immediately in the corresponding stream
constructor.

All other callbacks have spec text of the form:

    Throwing an exception is treated the same as returning a rejected
    promise.

And indeed this is internally handled by the streams spec. Thus all of
those callbacks can be specified as returning only a promise, rather
than a WebIDL::ExceptionOr<Promise>.

559d983fa1 LibWeb: Implement AO readable_stream_pipe_to()
This is currently a naive implementation of readable_stream_pipe_to()
which will need some further iterations before it is par with the spec.

This just sets up the plumbing to the underlying ReadableStreamTee AO,
which as of this commit, will just throw a NotImplemented exception.

9d0700e770 LibWeb: Fix IDL getter for ReadableByteStreamController byobRequest
We were previously only returning the controllers current
[[byobRequest]] instead of taking into account pending pull intos.

Rename the getter function which would return the controllers
[[byobRequest]] slot to `raw_byob_request` to differentiate it from
the IDL getter.

This also leaves a FIXME for a spec step which we are also not currently
implementing correctly.

673329e1bd LibWeb: Use ArrayBufferView for ReadableStreamBYOBReader
Which means that we now have support for DataViews.

Using the ArrayBufferView class also seems to make this read a whole

446a78f30e LibWeb: Implement Streams AO ReadableStreamAddReadIntoRequest
This is effectively identical to ReadableStreamAddReadRequest besides
from the fact that it takes a ReadIntoRequest instead of a ReadRequest,
and is instead intended to be used for BYOB readers.
