Compositor: Full frame Bokeh Blur and Blur nodes

Adds full frame implementation to these nodes operations.

When enabling "extend bounds" node option, tiled implementation
result is slightly different because it's using `TranslateOperation`
with bilinear sampling for centering.
Full frame always uses nearest to don't lose image quality.
It has the disadvantage of causing image jiggling on backdrop
when switching size values as it's not pixel perfect.
This is fixed by rounding to even.

No functional changes.

Part of T88150.
