More tiling checks

[jenshannoschwalm]

Fix logical typo for OpenCL fast tiling fitting check

We may not tile if the piece->tiling ready flag is not TRUE. (This requires the module->flags including IOP_FLAGS_ALLOW_TILING)

Fix some iop modules to support tiling

The algorithm of these modules allow tiling mode both for OpenCL and CPU. A special tiling_callback() is not required as the default meets requirements. (As these modules have low mem requirements it was not evident performance-wise on most systems).

I got aware of this via late comments by @kofa73 and his bots in #22100 (comment)

And - yes - we must respect the IOP_FLAGS_ALLOW_TILING flag in all cases.

@TurboGit @masterpiga (colorharmoniter) @jandren (contrastntexture) @kofa73 (agx) @MStraeten, if any of us adds new iop modules we must always check

1. if the module algorithm supports tiling at all add IOP_FLAGS_ALLOW_TILING
2. possibly override this if OpenCL doesn't do that or other preconditions in commit_params()
3. check if a dedicated tiling_callback() is required

Thanks!

Thank, Hanno, for updating AgX! LGTMATB (Looks good to me - and the bots) :-) Sorry, I was working and unable to comment before.
