feat: sealer build supports lite mode option

[kakaZhou719]

Describe what this PR does / why we need it

In some case, some applications do not need to store additional container images. it is faster and smaller.

so, at build stage, sealer could try to skip download container image through build mode option.

if it is lite, will skip download container image. default value is all, means download all container image.

how to use:

sealer build -t abc:v1 --build-mode=lite
sealer build -t abc:v1 --build-mode=lite --platform linux/arm64
sealer build -t abc:v1 --build-mode=lite --platform linux/amd64,linux/arm64
