Other changes:
- enable SSL support (corresponding knob is removed)
- enable PCRE2 support (PCRE, PCRE2, REGEX, NOPCRE knobs are removed)
- add QuickJS library as a dependency for the unitd+njs build
The unitd OTel support is the rust-based software. I was inspired
by the devel/xtensa-esp-elf/Makefile, so create the corresponding
solution.
<ChangeLog>
*) Feature: initial OpenTelemetry (OTEL) support. (Disabled by default).
