1. verifiers: generate built-in claims from quotes …

   In order to simplify the process of matching of Attestation Policy in user code, and to avoid user code dependencies on TEE-specific headers files / structs definitions, we convert quotes into built-in claims. These claims will be checked by user's verifier callback (verify_claims_callback) along with the user-defined claims.
   
   Now that we have categorized these claims into (user defined) custom claims and built-in claims.
   
   For built-in claims, they are:
   
   - `common_quote_type`, `common_quote`
   - `tdx_*`
   - `sgx_*`
   - `sev_snp_*`
   - `csv_*`
   
   Note that some break changes are interduced in this commit:
   
   The old claim name in tdx verifier
   ```c
       #define TDX_CLAIM_RTMR0 "rtmr0"
       #define TDX_CLAIM_RTMR1 "rtmr1"
       #define TDX_CLAIM_RTMR2 "rtmr2"
       #define TDX_CLAIM_RTMR3 "rtmr3"
   ```
   are renamed to "tdx_rtmr0", "tdx_rtmr1", "tdx_rtmr2", "tdx_rtmr3".
