redhat/configs: enable CONFIG_TCG_SVSM
The driver for the vTPM emulated by SVSM is needed for Confidential VMs. It's currently only supported by AMD SEV-SNP, which is why it's x86 specific, since it depends on CONFIG_AMD_MEM_ENCRYPT.

First time contribution for me here, I guess I need this for https://gitlab.com/redhat/centos-stream/src/kernel/centos- stream-9/-/merge_requests/7004
Please let me know if I need to do something different.
