Add an extra "../" to the relative paths so that the uAPI headers
provided by tools can be found correctly.

Since commit ceea279f9376 ("perf kvm stat: Remove use of the arch
directory"), a native build on Arm64 machine reports:
util/kvm-stat-arch/kvm-stat-x86.c:7:10: fatal error: asm/svm.h: No such file or directory
7 | #include <asm/svm.h>
| ^~~~~~~~~~~
compilation terminated.
The build fails to find x86's asm headers when building for Arm64. Fix
this by including asm headers with relative path instead.

Pass the e_machine to the kvm functions so that they aren't just wired
to EM_HOST.
In the case of a session move some setup until the session
is created.
As the session isn't fully running the default EM_HOST is returned as no
e_machine can be found in a running machine.
This is, however, some marginal progress to cross platform support.

`perf kvm stat` supports record and report options.
By using the arch directory a report for a different machine type cannot
be supported.
Move the kvm-stat code out of the arch directory and into
util/kvm-stat-arch following the pattern of perf-regs and dwarf-regs.
Avoid duplicate symbols by renaming functions to have the architecture
name within them.
For global variables, wrap them in an architecture specific function.
Selecting the architecture to use with `perf kvm stat` is selected by
EM_HOST, ie no different than before the change.
Later the ELF machine can be determined from the session or a header
feature (ie EM_HOST at the time of the record).
The build and #define HAVE_KVM_STAT_SUPPORT is now redundant so remove
across Makefiles and in the build.
Opportunistically constify architectural structs and arrays.
