Rollup merge of #56713 - xfix:vec-test-zst-capacity, r=TimNN
Test capacity of ZST vector
Initially, #50233 accidentally changed the capacity of empty ZST. This was pointed out during code review. This commit adds a test to prevent capacity of ZST vectors from accidentally changing to prevent that from happening again.
