configure.ac, src/: add C++20, add new stackprof tool

eu-stackprof is a new tool which profiles processes on a Linux system
using perf_events and outputs gprof gmon.out format program counter
histograms and callgraph-arc profiles; intended as an updated demo of
libdwfl_stacktrace functionality and as a data-gathering tool for the
profiledb initiative.

* configure.ac: Add configure checks for C++20, eu-stackprof
  perf/libpfm dependencies.
* config/elfutils.spec.in: Add stackprof.
* po/POTFILES.in: Add stackprof.cxx.
* src/Makefile.am (bin_PROGRAMS): Add stackprof.
  (stackprof_*): Add stackprof SOURCES, LDADD, and so forth.
* src/stackprof.cxx: New file.

tests/: add test suite for stackprof

Together with the stackprof tool we add some test cases to exercise
it, and the underlying libdwfl_stacktrace functionality as well.

  perf_events availability and verifying gmon.*.out files.
* tests/run-stackprof-system.sh: New file.
* tests/run-stackprof-system-gprof.sh: New file.
* tests/run-stackprof-user.sh: New file.

* tests/Makefile.am (TESTS): add the new testcases.

src/stacktrace.c: remove in favour of stackprof

Now that stackprof is added, the existing src/stacktrace.c tool is
officially obsolete as a demo -- it relies on a custom patchset for
Sysprof (communicating via pipe, not contributed to mainline, in
favour of the sysprof-live-unwinder tool which links elfutils as a
library), whereas stackprof pulls data from perf_events directly.

Likewise, stackprof includes all of the eu-stacktrace functionality
for logging/statistics.

* configure.ac: Remove eu-stacktrace related bits.
  The configure checks for stackprof are simpler (just perf_events.h
  and libpfm).
* config/elfutils.spec.in: Remove eu-stacktrace.
* po/POTFILES.in: Remove stacktrace.c.
* src/Makefile.am: Remove eu-stacktrace related bits.
* src/stacktrace.c: Remove.
* .forgejo/workflows/check-fedora.yaml: Remove sysprof-capture-devel.
