package:test v1.31.0

• Print a summary of failed tests at the end of the expanded reporter output.
• Add vm-asan, vm-msan, and vm-tsan runtimes to run tests on the standalone
  Dart VM under Address Sanitizer, Memory Sanitizer or Thread Sanitizer. This is
  useful for finding issues when using foreign libraries through dart:ffi, such
  as use-after-free, use of initialized memory and data races, or for detecting
  data races in Dart code using shared fields.
• Change return type on the body callback argument to group to void from
  dynamic. This may surface cases where the group callback was erroneously
  returning an ignored value.
• Fix a hang when a test run with --compiler exe crashes.
• Require analyzer: '>=8.0.0 <13.0.0'
