Add tests of tracing SystemC model verilated with --hierarchical (#3252) 
* Tests: Add t_hier_block_sc_trace(fst|vcd) that tests tracing hierarchical block on SystemC.

* Add a check that elaboration is done before a trace file is opened.

* Add a check that elaboration is done before trace() is called to verilated SystemC model.

* Tests: call sc_core::sc_start(sc_core::SC_ZERO_TIME) before opening a trace file

* Tests: Fix t_trace_two_sc to call sc_start before opening trace

* Use vl_fatal as suggested in PR review.

Geza Lore 1de2de4bde Fix splitting of large _eval and related functions 
Fix bug that only used to measure size of first statement in functions
to determine if splitting was necessary. Measure whole function instead.

Reduce .rodata footprint of trace initialization (#3250) 
Trace initialization (tracep->decl* functions) used to explicitly pass
the complete hierarchical names of signals as string constants. This
contains a lot of redundancy (path prefixes), does not scale well with
large designs and resulted in .rodata sections (the string constants) in
ELF executables being extremely large.

This patch changes the API of trace initialization that allows pushing
and popping name prefixes as we walk the hierarchy tree, which are
prepended to declared signal names at run-time during trace
initialization. This in turn allows us to emit repeat path/name
components only once, effectively removing all duplicate path prefixes.
On SweRV EH1 this reduces the .rodata section in a --trace build by 94%.

Additionally, trace declarations are now emitted in lexical order by
hierarchical signal names, and the top level trace initialization
function respects --output-split-ctrace.
