arch/x86: Add API to check if cache sets are power-of-two

Introduce a function to determine whether the number of cache sets is
a power of two. This aligns with common cache design practices that
favor power-of-two counts for efficient indexing and addressing.

BUG=b:306677879
BRANCH=firmware-rex-15709.B
TEST=Verified functionality on google/ovis and google/rex (including
a non-power-of-two Ovis configuration).
