Elliot Lee c2b03fecca Remove recipe for RocksDB and add recipe for Snappy (#4431)
- Copies the recipe for Snappy from Conan Center, but removes three
  lines that explicitly link the standard library, which prevents
  builders from statically linking it.
- Removes the recipe for RocksDB now that an official recipe for version
  6.27.3 is in Conan Center.

Developers will likely need to remove cached versions of both RocksDB
and Snappy:

```
conan remove -f rocksdb
conan remove -f snappy
```
