fix: make Errors match with ordinary objects (fixes #5359)

[kpsroka]

Summary

Fixes #5359 -- makes toMatchObject work when comparing Errors with ordinary objects. This is accomplished by extending subset matching algorithm to include prototype properties of the object under test.

Test plan

Added two test cases in matchers.test.js. No other tests were modified.
However, yarn test fails with the following error:

  ● exceeds the timeout

    expect(received).toMatch(expected)
    
    Expected value to match:
      /(jest\.setTimeout|jasmine\.DEFAULT_TIMEOUT_INTERVAL|Exceeded timeout)/
    Received:
      "PASS __tests__/a-banana.js
      ✓ banana
    
    "

Bonkers. Let's see if CI catches that one too.
