Change default thread pool sizes to respect processor affinity (#6604)
Instead of using the number of processors in the host, use the number of
processors available to the process, respecting cpu affinity
assignments. Without pthreads, fall back and use the number of
processors in the host as before.

This is now applied everywhere so runing `nuamctl -C 0-3 verilator` or
`numactl -C 0-3 Vsim` should behave as if the host has 4 cores (e.g.
like in CI jobs)

Geza Lore a09506a0ad Trivial simplification of V3EmitCModel
Still some remains of the --threads 0 mode. Remove unnecessary complexity
from V3EmitCModel. (Also don't pretend there is an MTask in single
threaded mode, when there really isn't.)

Geza Lore b78ea06829 Make VL_LOCK_SPINS configurable
It's unlikely one value fits all use case, so making VL_LOCK_SPINS
configurable at model build time.

For testing, we reduce the value as we expect high contention.

Add prepareClone and atClone APIs for Verilated models (#3503) (#4444)
This API is used if the user copies the process using `fork`
and similar OS-level mechanisms. The `at_clone` member function
ensures that all model-allocated resources are re-allocated, such
that the copied child process/model can simulate correctly.

A typical allocated resource is the thread pool, which every model
has its own pool.

Geza Lore 0e769d42a1 Optimize trigger evaluation
Pack the elements of VlTriggerVec as dense bits (instead of a 1 byte
bool per bit), and check whether they are set on a word granularity.
This effectively transforms conditions of the form `if (trig.at(0) |
trig.at(2) | trig.at(64))` into `if (trig.word(0) & 0x5 | trig.word(1) &
0x1)`. This improves OpenTitan ST by about 1%, worth more on some other
designs.
