arch/cc: Introduce a function to check for confidential computing features
commit 46b49b12f3fc5e1347dba37d4639e2165f447871 upstream.
In preparation for other confidential computing technologies, introduce
a generic helper function, cc_platform_has(), that can be used to
check for specific active confidential computing attributes, like
memory encryption. This is intended to eliminate having to add multiple
technology-specific checks to the code (e.g. if (sev_active() ||
tdx_active() || ... ).
