ta: pkcs11: be flexible on RSA private key optional attributes

Allow RSA private key to partially store the RSA private key optional
attributes without facing complaints from the GP TEE API.

On one hand, in the PKCS#11 specification, RSA private key attributes
CKA_PRIME_1, CKA_PRIME_2, CKA_EXPONENT_1, CKA_EXPONENT_2 and
CKA_COEFFICIENT are optional and the spec does not add much constraints
on their presence.

On the other hand, the GP TEE Internal Core API requests that these
5 optional attributes are all present or none is present at all.

As a trade-off, allow PKCS#11 client to partially provide them but do not
load them into the TEE object unless they are all present.

Sign and verify operations are processed using TEE decrypt/encrypt
operation since GP TEE Internal Core API specification only allows
these modes for TEE_ALG_RSA_NOPAD algorithm. The pkcs11 TA only support
sign operation when the provided payload is exactly of the same size
as the RSA key used and checks the generate signature is of right size.

This mechanism can be needed to support CKM_RSA_X_509 for TLSv1.2
connections.

Add CFG_PKCS11_TA_RSA_X_509 to allow configuring the pkcs11 TA
with or without raw RSA crypto support. The config switch is default

ta: pkcs11: write db_main and db_objs in one operation

Problem:
There is a potential issue in persistent_token.c::init_persistent_db().
There are two steps to initialize a token DB if it doesn’t exist:
1. Call TEE_CreatePersistentObject() with db_main as the initial data.
2. Truncate the object data and then insert db_obj data.
If a power loss occurs between above two steps, only the db_main data is
present in the database. When the device restarts, it detects the existing
database and successfully reads db_main, but fails to read db_obj, leading
to a TA panic each time.
https://github.com/OP-TEE/optee_os/issues/6977

Solution:
Write both db_main and the initial 4 bytes of db_objs (with a count of 0)
in a single operation during TEE_CreatePersistentObject().

ta: pkcs11: implement AES GCM operations

Implement AES GCM authenticated encryption and decryption.

AES GCM decryption requires that the output data is revealed only once
decryption is finalized and the MAC signature successfully verified.
For this operation, the AES GCM context references a dynamically
allocated data buffer to store output data as they are generated by
each call to TEE_AEUpdate().

AES GCM one-shot operation in the pkc11 TA is a bit specific in that
it requires an extra TEE operation handle to save the initialized
operation state in case of one shot processing request (C_Encrypt()
or C_Decrypt() cryptoki API functions) that queries the output buffer
size. GP TEE Internal Core API does not define a single API function
for such one shot operation that could be called to query the output
buffer size. We must first fully process the input data (TEE_AEUpdate())
before we can query the output buffer size with TEE_AEEncryptFinal() or
TEE_AEDecryptFinal(). Consequently we will need to process again the
input data when client provides a well sized output buffer as we are not
sure that input data will be the same. Therefore the implementation
allocates a 2nd operation handle, copy the operation state into after
it is initialized and use this context to restore this initial state in
case the one shot AE operation is returning PKCS11_CKR_BUFFER_TOO_SMALL.
