Change TRACY_ENABLE default to OFF to match documentation.

The documentation states that Tracy is disabled by default, but the
build system defaults were ON/true. Change CMake and Meson defaults to
OFF/false. Projects that need profiling enabled must now opt in
explicitly. Add explicit TRACY_ENABLE=ON / tracy_enable=true to CI
steps and the test project to preserve existing behavior.
