Reapply "Use R8 for resource shrinking"

This reverts commit a9fd59a7f28df05f9d75bda7d661241e4d1a3f6a.

We are moving the resource shinking pipeline into r8 (gennerally, not just for platform)

This disables the usage of the resource shrinker cli from cmd-line tools

There are no changes in this cl compared to the original land, the fix
was done in R8 (to use the same compression for res folder entries as
in the original)

Bug: 308710394
Bug: 309078004
Test: Existing, validated that resource table on SystemUI was byte<>byte equal, validated uncompression

Ignore-AOSP-First: Merge does not apply cleanly
