Version upgrade to v1.0-rel0

[bokdeuk-jeong]

The most recent version of qemu-rme at Building an RME stack for QEMU - Enable Arm Architecture in QEMU - Confluence is based on CCAv1.0-rel0.

As a part of some tests to see if our current Islet, which is based on 1.0-eac5, can be running on the current qemu-rme(v4), I ran requried sw , tf-rmm(v3) with a minor change, kvmtool(v2) and linux(v4), which seem to be for versions lower than 1.0-rel0.
I managed to run tf-rmm and the host, but failed to launch a realm with an error below:
KVM_CAP_RME(KVM_CAP_ARM_RME_CONFIG_REALM) hash_algo: Invalid argument.

So rather than figuring out the proper combination of sw stack, I propse to upgrade Islet to v1.0-rel0. One way or the other, we will need this soon.
While some work on the version upgrade, others may use islet with 1.0-eac5 on fvp or tf-rmm with 1.0-rel0 on qemu.
I expect this shouldn't take long--at mot, a month.

The scope of work is as follows:

1. First, implement RMIs and RSIs according to the spec v1.0-rel0.
2. Second, update the implementation reflecting the defect resolution the spec in 1.1.
3. Third, platform spefic implementation for qemu.

Please share your thoughts on this.

I propse to upgrade Islet to v1.0-rel0.

I agree. Because sooner or later we should update islet to meet the latest CCA spec

There are small changes in the attestation token format concerning how the RAK key is encoded. In the scope of our project we'll have to adjust rust-rsi. As to the other components that we're depend on, at first glance it seems that Veraison already provides support for this new token format: veraison/ccatoken@b8e6d26
