Add bitcoin-hashes-std features

Currently we use 'no default features' for the `bitcoin_hashes`
dependency. Doing so means that if users want the `std` feature they
need to explicitly add a `bitcoin_hashes` dependency even though we
re-export `bitcoin_hashes` as `hashes`. This means that in the common
case the re-export is pointless. As an example, `rust-bitcoin`
unnecessarily requires an explicit dependency on `bitcoin_hashes`.

Add `bitcoin-hashes-std` feature so that users do not need an explicit
dependency in the common use case.

Change the test matrix to only test '*-std' features when 'std' is
enabled since enabling one without the other is illogical. Please note,
this replaces the test run of feature 'std'+'rand'+'rand-std' with just
'std'+'rand-std' because enabling 'rand-std' enables 'rand' so the
explicit additional feature is redundant.
