Also remove existing symlink_forest_version functionality. This remedies issues pertaining to b/300122962 - symlinks not clearing after a revert Timing wise - this doesn't present a performance regression on a clean build. When soong_build changes, it's considerably longer but no different from the time when symlink_forest_version is changed. Bug: 300288299 Test: build/soong/tests/symlink_forest_rerun_test.sh Change-Id: I0e95aac315dfea7ea3b8bb9a3eb0c6408300bd3b
