feat: Update Tile Pre-Processor to support more modes

[blessedcoolant]

Summary

Add support for more methods of resampling to work with Tile ControlNet models.

• regular - The default downsizing resampler which basically downsamples the input image.
• blur - A new guided filter algorithm that works with the now available ControlNet models for SDXL.
• var - Used for image variations apparently
• super - TODO -- used with super sizing but probably should not be in this particular node anyway

Tile Image Processor is now also available in the Linear UI.
