Fix ~144 single-word typos in arch/x86/ code comments.
Doing this in a single commit should reduce the churn.

Use x2apic_mode instead of x2apic_enabled() when adjusting the
destination ID during Posted Interrupt updates. This avoids the costly
RDMSR that is hidden behind x2apic_enabled().

KVM: VMX: Extract posted interrupt support to separate files
added another pi_init(), though one already existed in the paride code.

Extract the posted interrupt code so that it can be reused for Trust
Domain Extensions (TDX), which requires posted interrupts and can use
KVM VMX's implementation almost verbatim. TDX is different enough from
raw VMX that it is highly desirable to implement the guts of TDX in a
separate file, i.e. reusing posted interrupt code by shoving TDX support
into vmx.c would be a mess.
