target/i386: add support for masking CPUID features in confidential guests

Some CPUID features may be provided by KVM for some guests, independent of
processor support, for example TSC deadline or TSC adjust.  If these are
not supported by the confidential computing firmware, however, the guest
will fail to start.  Add support for removing unsupported features from
"-cpu host".
