feat(medusa,inventory,types): Expand list-reservation capabilities (#3979)

**What**
- Add filter capabilities to reservation items based on: 
  - description query: "contains", "startsWith", "endsWith", "equals"
  - date querying

**How**
- Introducing a new filtering primitive: "StringSearchOperator" resembling the "dateComparisonOperator"

Fixes CORE-1373
