The evsel argument to evsel__intval, evsel__rawptr, and similar
functions, is unnecessary as it can be read from the sample. Remove
the evsel and rename the function to match that the data is coming
from the sample.

As struct perf_sample now directly contains its own resolved evsel pointer,
passing the evsel separately is redundant and clutters the interface.
Remove the redundant evsel parameter from kvm-specific handlers and
structures, ensuring the tool always directly accesses the evsel bound to the
sample. This simplifies the API signatures and eliminates the risk of passing
an inconsistent evsel.

Add an extra "../" to the relative paths so that the uAPI headers

Since commit ceea279f93 ("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.
