perf util: Make util its own library

Make the util directory into its own library. This is done to avoid
compiling code twice, once for the perf tool and once for the perf
python module. For convenience:
arch/common.c
scripts/perl/Perf-Trace-Util/Context.c
scripts/python/Perf-Trace-Util/Context.c
are made part of this library.

perf tests arm64: Compile tests unconditionally

In order to subsequently add more tests for the arm64 architecture we
compile the tests target for arm64 systematically.

Further explanation provided

perf tests arm64: Compile tests unconditionally

In order to subsequently add more tests for the arm64 architecture we
compile the tests target for arm64 systematically.

Further explanation provided by Mark Rutland:

Given prior questions regarding this commit, it's probably worth
spelling things out more explicitly, e.g.

Currently we only build the arm64/tests directory if
CONFIG_DWARF_UNWIND is selected, which is fine as the only test we
have is arm64/tests/dwarf-unwind.o.

So that we can add more tests to the test directory, let's
unconditionally build the directory, but conditionally build
dwarf-unwind.o depending on CONFIG_DWARF_UNWIND.

There should be no functional change as a result of this patch.

perf build: Add arch x86 objects building

Move the x86 arch objects building under build framework to be included
in the libperf build object.

Adding also arch/$(ARCH)/Build files for the rest of the archs. The
reason for this is that in arch/Build we now do:

+libperf-y += $(ARCH)/

which would make the build to fail on other architectures, because the
build framework requires 'Build' file in nested directories and this
patch adds it only for x86.
