[PATCH v5 04/13] KVM: x86: Move enable_pmu/enable_mediated_pmu to pmu.h and pmu.c

[Yosry Ahmed <yosry@kernel.org>]

The declaration and definition of enable_pmu/enable_mediated_pmu
semantically belongs in pmu.h and pmu.c, and more importantly, pmu.h
uses enable_mediated_pmu and relies on the caller including x86.h.

There is already precedence for other module params defined outside of
x86.c, so move enable_pmu/enable_mediated_pmu to pmu.c.

No functional change intended.
