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.

Add simulation context (VerilatedContext) (#2660). (#2813) 
**   Add simulation context (VerilatedContext) to allow multiple fully independent
      models to be in the same process.  Please see the updated examples.
**   Add context->time() and context->timeInc() API calls, to set simulation time.
      These now are recommended in place of the legacy sc_time_stamp().

Fix memory leaks when using shared protect-lib (#2707) 
* Guarantee mechanism to initialize just once is now in VerilatedInitializer. No functional change is intended.

* Make sure to initialize Verilated::NonInitialized just once. Fixes
memory leak in t_prot_lib_shared and t_hier_block_prot_lib_shared.
