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".

Summary
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.
Currently SGX, TDX, SEV-SNP, CSV verifiers are supported.
For built-in claims, they are:
