[TF-M] Set PSA_2_0_0 as default attest profile and removal of PSA_IOT_PROFILE_1

Hi,

We are going to set the PSA_2_0_0 profile as the default for the initial attestation service. This will impact which claims are included in the token and their key values.

More details are here: https://www.ietf.org/archive/id/draft-tschofenig-rats-psa-token-24.html

Changes on review: https://review.trustedfirmware.org/q/topic:%22attest_profile_update%22

As a follow-up action, the PSA_IOT_PROFILE_1 is being deprecated.

We are planning to remove it from the code base as well. To figure out the timing of this we would like to collect some data:

* If you are using the PSA_IOT_PROFILE_1 please let us know what would be a feasible time for you to switch over the PSA_2_0_0 profile. Thanks!

Best regards, Tamas Ban
