Move the virHostPMCapability enum helpers into capabilities.c

The virHostPMCapability enum helper was declared in util.h
but implemented in capabilities.c, which is in a completely
separate library at link time. Move the declaration into the
capabilities.c file and rename it to match normal conventions

* src/util/util.h: Remove virHostPMCapability enum decl
* src/conf/capabilities.c: Add virCapsHostPMTarget enum
