stream: use validateBuffer for BYOB reader view

[greenheadHQ]

ReadableStreamBYOBReader.prototype.read() open-codes the check that validateBuffer performs, while ReadableStreamBYOBRequest.prototype.respondWithNewView() a few hundred lines above already calls validateBuffer(view, 'view') for the same argument. Both build ERR_INVALID_ARG_TYPE from the same name and type list, so the rejection is unchanged.

No new test: readable-byte-streams/general.any.js already covers read() with a non-view argument.

The aarch64-darwin: with shared libraries failure is unrelated to this change. It is parallel/test-stream-pipeline-http2, which is listed as flaky in nodejs/reliability#1622. The same commit passes on every other platform, including x86_64-darwin, and the test does not touch web streams.

@daeyeon It looks like the queue stopped because Jenkins CI hadn’t run yet. When you have a chance, could you help trigger the full CI? Thanks for looking into this! 🫡
