Every write() and writeSync() allocated a `{ __proto__: null, context }`
options object for the WebIDL chunk conversion, and for a Uint8Array
chunk a second, six-property one with [AllowShared] and
[AllowResizable]. Both are created in V8 dictionary mode.
Return Uint8Array chunks directly from the WriterChunk converter: with
[AllowShared] and [AllowResizable], the Uint8Array conversion cannot
reject a value isUint8Array() accepts and returns the same object. Use
shared, frozen conversion contexts for chunks, chunk sequences and
write options; the converters only read them to build error messages.
Writing 1e6 16-byte Uint8Array chunks into a push() stream and reading
them back is about 27% faster with writeSync() and with writevSync()
(4 chunks per call). String chunks are unaffected. Behavior and error
messages are unchanged.
