refactor: take a uint8_t span in ValidateIntegrityOrDie() (#43592)
refactor: take a uint8_t span in ValidateIntegrityOrDie()

Doing some groundwork for fixing unsafe base::File() APIs:

- Change ValidateIntegrityOrDie() to take a span<const uint8_t> arg.
  We'll need this to migrate asar's base::File API calls away from the
  ones tagged `UNSAFE_BUFFER_USAGE` because the safe counterparts use
  span<uint8_t> too.

- Simplify ValidateIntegrityOrDie()'s implementation by using
  crypto::SHA256Hash() instead of reinventing the wheel.
