Enable to build confidential guests using ARM CCA (Confidential Computing Architecture). This work relies on v7 series for Linux and v5 series for KVM. This has been tested only on the corresponding FVP model simulator. For testing, you require specific kvm-ioctls and kvm-bindings crates.

This PR aims at adding support to build realm guests. First commit adds support for
create_guest_memfd()andset_user_memory_region2(). To do this, thememory_init()is modified by adding a boolean parameter. This is required when building a confidential guest for arm cca and probably also required by other cases.The second commit imports the
virtee/ccacrate and adds the steps to build a cca guest. The following items should be completed before merge the PR:This has been testing using the v7 series for Linux as a guest and v5 series for KVM on FVP model.
Feedback is welcome.
