KVM: SVM: Implement and adopt VMX style MSR intercepts APIs

Add and use SVM MSR interception APIs (in most paths) to match VMX's
APIs and nomenclature.  Specifically, add SVM variants of:

        vmx_disable_intercept_for_msr(vcpu, msr, type)
        vmx_enable_intercept_for_msr(vcpu, msr, type)
        vmx_set_intercept_for_msr(vcpu, msr, type, intercept)

to eventually replace SVM's single helper:

        set_msr_interception(vcpu, msrpm, msr, allow_read, allow_write)

which is awkward to use (in all cases, KVM either applies the same logic
for both reads and writes, or intercepts one of read or write), and is
unintuitive due to using '0' to indicate interception should be *set*.

Keep the guts of the old API for the moment to avoid churning the MSR
filter code, as that mess will be overhauled in the near future.  Leave
behind a temporary comment to call out that the shadow bitmaps have
inverted polarity relative to the bitmaps consumed by hardware.

No functional change intended.
