Add experimental reuse of non-worker sandboxes.
This uses the same functionality as the worker sandboxing to reuse existing sandboxing. Where the worker sandboxes just stay in place, for non-worker sandboxes we move each sandbox aside after use, then move them back to the new sandbox location when we want to reuse them. When reusing a sandbox, we traverse the reused directory and remove anything that doesn't match what we want for the new action.
Timing on Mac of degenerate case from GitHub issue #8230, last 20 of 40 builds:
- `--strategy=standalone`: Avg. 8.45s
- `--strategy=sandbox`: Avg. 56.09s (+563%)
- `--strategy=sandbox --experimental_reuse_sandbox_directories`: Avg. 10.72s (+27%)
RELNOTES: Adds --experimental_reuse_sandbox_directories flag to reuse already-created non-worker sandboxes with cleanup.
