util: perf: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

Browse Source 
Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.

When a variable of type virPerfPtr is declared using VIR_AUTOPTR,
the function virPerfFree will be run automatically on it when it
goes out of scope.

This commit also adds an intermediate typedef for virPerf
type for use with the cleanup macros.
