Michael Jeanson 536e81f074 perf data ctf: replace libbabeltrace with babeltrace2-ctf-writer 
The 1.x branch of Babeltrace has been superseded by 2.x in 2020 and has
been unmaintained since 2022, efforts have started to remove it from
popular distributions.

Babeltrace 2.x offers a very similar 'ctf-writer' library that can be used
with minimal changes for the '--to-ctf' feature and has been packaged
since Debian 11 and Fedora 32.

This patch replaces the 'libbabeltrace' build feature with
'babeltrace2-ctf-writer' using pkgconfig detection, adjusts the naming of
the public headers and applies minor API cleanups.

There is no changes to the output ctf traces, the ctf-writer API still
implements version 1.8 of the CTF specification that can be read by
either Babeltrace 1 / 2 or any CTF compliant reader.

Also remove some ifdefs in the cli option parsing to allow printing the
helpful error message with '--to-ctf' when built without babeltrace2.
