[release/1.4.16] tests: update test files from github.com/ethereum/tests @ 45bc1d21d3c1

Two new tests are skipped because they're buggy. Making some newer
random state tests work required implementing the 'compressed return
value encoding'.

(cherry picked from commit 1b7b2ba2163c7b2b2acc0c4f107951ad873cd8a4)
