Draft: Fix RSA key generation issue for Corstone-1000

When running parsec test, it reports an error PSA_ERROR_DATA_INVALID (-153).

This is related to ITS_MAX_ASSET_SIZE configuration which is been set to 512 on the secure enclave (TF-M), which defines the max asset size overflowing when running the parsec test.

The key is generated, but when it is asked to store via psa_its_set it returns PSA_ERROR_INVALID_ARGUMENT (-135), which then propagates to PSA_ERROR_DATA_INVALID (-153)

Increasing the ITS_MAX_ASSET_SIZE to 2048 solves this issue.
