Merge #21438: test: add ParseUInt8() test coverage

Browse Source 
76782e560b refactor: reuse test string with embedded null char in util_tests (Jon Atack)
24c6546946 test: add ParseUInt8() unit and fuzz test coverage (Jon Atack)

Pull request description:

  We have unit test and fuzzer coverage for
  - `ParseInt64()`
  - `ParseInt32()`
  - `ParseUInt64()`
  - `ParseUInt32()`

  but not `ParseUInt8()`, so this pull adds it.

  I was tempted to add a commit that applies clang formatting to the file, or one that updates the C-style casts to named casts, but resisted the temptation unless reviewers request it.
