Fixes: #65085

Detached ArrayBuffers were rejected with ERR_INVALID_ARG_VALUE, but detached views were not: typed arrays exported zero bytes and DataViews threw a bare TypeError from byteLength.

Track detachment in ArrayBufferViewContents::Read() and skip the JS length check for detached buffers, so every detached input is rejected.

ffi: reject detached ArrayBufferViews
f2c8454
Detached ArrayBuffers were rejected with ERR_INVALID_ARG_VALUE, but
detached views were not: typed arrays exported zero bytes and DataViews
threw a bare TypeError from byteLength.
Track detachment in ArrayBufferViewContents::Read() and skip the JS
length check for detached buffers, so every detached input is rejected.

ffi: reject detached ArrayBufferViews
f2c8454
Detached ArrayBuffers were rejected with ERR_INVALID_ARG_VALUE, but
detached views were not: typed arrays exported zero bytes and DataViews
threw a bare TypeError from byteLength.
Track detachment in ArrayBufferViewContents::Read() and skip the JS
length check for detached buffers, so every detached input is rejected.
