Maksym Pavlenko f52e748f16 ctr: add build-erofs-cache to populate the erofs layer cache ...

Add `ctr images build-erofs-cache <image> <cache_dir>`, which reads an
already-pulled image's layers from the content store, converts each into a
directly-mountable erofs blob, and writes them under
<cache_dir>/<algorithm>/<hex>.erofs keyed by the layer's diffID. This
populates the directory the erofs snapshotter's layer_content_cache reads
on pull; because the key is the source diffID, layers shared across images
converge on one blob. No converted image is produced.

Extract the per-layer uncompress + mkfs.erofs step out of LayerConvertFunc
into an exported ConvertLayerToErofs so the image converter and the cache
builder share a single conversion path.
