FLEDGE: Add mapping from ad to size groups to joinAdInterestGroup().

In https://crrev.com/c/4167800, these mappings are added:
1. size groups --> ad size names
2. ad size names --> blink::AdSize

This CL adds the mapping: ad --> size group

Note:
1. FindMatchingAd is updated. Two ads are considered matching if:
  a. They have the same url, and neither has any size specified.
  b. They have the same url, and both have the same size specified.

2. Updated IDL, serialize/deserialize implementations, copy from IDL
   functions and InterestGroupAd mojom/mojom traits.

3. Added the builder pattern setters for ad size and size groups.
4. Added unit tests and browser tests.
5. The next CL will implement the macro substitution of sizes into
   the mapped url in fenced frame mapping, when auction is completed.
