Fix #33650: Compositor locks up when input is an unrendered render layer.

Issue was caused by resolution detecting which assumed zero resolution is
undefined one and should be re-evaluated. It doesn't work in cases when
there's a missing input, causing lots of unneeded resolution re-calculation.

It wasn't so much issue in average sized node trees, but it was a real
problem in generated tree from the report.

Currently used pretty simple solution which added a boolean flag to the
node operation which signal whether resolution was ever set or not.

There're probably smarter solutions here but can not think about them.
