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.

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.

9907d211ff Make VlWide and VlUnpacked C++20 compatible aggregates. 
C++20 requires that aggregate types do not have a user declared
constructor, not even an explicitly defaulted one. We need these types
to be aggregates for static initialization.

Fixes #3076.

Implement a distinct constant pool (#3013) 
What previously used to be per module static constants created in
V3Table and V3Prelim are now merged globally within the whole model and
emitted as part of a separate constant pool. Members of the constant
pool are global variables which are declared lazily when used (similar to
loose methods).

Emit model implementation as loose methods. (#3006) 
This patch introduces the concept of 'loose' methods, which semantically
are methods, but are declared as global functions, and are passed an
explicit 'self' pointer. This enables these methods to be declared
outside the class, only when they are needed, therefore removing the
header dependency. The bulk of the emitted model implementation now uses
loose methods.

Introduce a macro VL_ATTR_NO_SANITIZE_ALIGN to suppress unaligned access check in ubsan (#2929) 
* Add VL_ATTR_NO_SANITIZE_ALIGN macro to disable alignment check of ubsan
