CanvasRenderingContext2DBase::getImageData with ImageDataStorageFormat
https://bugs.webkit.org/show_bug.cgi?id=284414
rdar://problem/141249363
Reviewed by Cameron McCormack.
`context.getImageData(..., {storageFormat:"float16"})` now works and
returns a Float16Array, which is currently converted from the canvas'
always-uint8 buffer.
`TypedArrayItemConverter<Float16Array, Uint8ClampedArray>::convert`
tweaked to round towards nearest (so 0.5 gets converted to 128), as
per specs https://github.com/w3c/ColorWeb-CG/blob/main/canvas_float.md
