This change actually migrates vm/dart/* tests to NNBD by fixing compile-time errors and adjusting tests where needed. vm/dart/null_float32x4_simd_ops_test and vm/dart/null_float64x2_simd_ops_test are deleted as they are superseded by static type checks. vm/dart/regress_40462_test.dart is a huge source code auto-generated by fuzzer and migrating and maintaining this source doesn't have much value, so it is deleted. There are still failures in strong mode due to dependencies on the packages which are not migrated yet (https://github.com/dart-lang/sdk/issues/42146). Migrated vm/dart/null_checks_with_dwarf_stack_traces_test fails both in weak and strong mode due to https://github.com/dart-lang/sdk/issues/42149.
