Expand Buf tests

[paolobarbolini]

After playing around with cargo-mutants I got confirmation that multiple bytes APIs are not tested, which in the past have lead to things like #138, b4ebe84 and #730. This general way of testing also makes it easier to test specializations like #481, which may be interesting to implement for some types in the future.

I've also conservatively deleted tests for things I could confirm were covered by the new ones.

This also increases test coverage from 67.2% to 72.2%.

If we like this approach the same could be done for BufMut.
