Support array and struct info metadata in FST traces (#7255) 
- Emit arrays under the new FST scope type FST_ST_SV_ARRAY
- Emit packed/unpacked 'array' attributes before FST_ST_SV_ARRAY,
  including left and right indices of the array
- Emit packed/unpacked 'pack' attributes before FST_ST_VCD_STRUCT and
  FST_ST_VCD_UNION, including the number of members in the types

All attributes apply to the immediately following scope definition (just
like enum dtype attributes).

Support jemalloc as the default allocator on Linux (#7250) 
Add jemalloc as an alternative malloc implementation for the Verilator
binary. When both tcmalloc and jemalloc are available, jemalloc is
preferred due to its better performance on RTLMeter.

The new --enable-jemalloc flag (default=check) mirrors the existing
--enable-tcmalloc behavior: auto-detected at configure time, supports
both static and dynamic linking, and is disabled when --enable-dev-asan
is active.

Tests: Consolidate format specific t_trace_* tests (#7216) 
Factor out test execution into t/trace_*_common.py, which defines
a 'run' functions. All related t_trace_*py tests call this function.

Behaviour is partially encoded in the file name, which must be of the
form: t_trace_complex_<variant>_<mode>_<format>*.py, where '<variant>'
determines tracing options (default/params/structs), '<mode>' is the
compilation mode (--cc/--sc), and '<format>' determines the trace format
(vcd/fst/saif).

The part of the test name after '<format>' does not influence the test
directly and can be free form. If used, explicit 'verilator_flags2' is
passed to the 'run' function.

Fix tracing of typedefed 1D packed arrays with --trace-structs (#7237) 
Used to incorrectly unroll 1D packed arrays of 'bit' or 'logic' into
elements when using --trace-structs if the array element type was given
via a typedef. Keep them as a single signal instead.
