Add syntactic sugar for "strong preferences" and "conflicts" (#41832) 
Currently requirements allow to express "strong preferences" and "conflicts" from
configuration using a convoluted syntax:
```yaml
packages:
  zlib-ng:
    require:
    # conflict on %clang
    - one_of: ["%clang", "@:"]
    # Strong preference for +shared
    - any_of: ["+shared", "@:"]
```
This PR adds syntactic sugar so that the same can be written as:
```yaml
packages:
  zlib-ng:
    conflict:
    - "%clang"
    prefer:
    - "+shared"
```
Preferences written in this way are "stronger" that the ones documented at:
