Wilson Snyder 4e49941b39 CI: Skip later CI on reformat 
Small chance a bug gets through, but this will avoid multiple runs on the
common case of reformatting users' pull requests, and related run
cancellation problems.

CI: Load RTLMeter cases to run from separate file (#7730) 
Add a script that prints the job matrix of cases to run with RTLMeter.
This enables running different sets based on parameters. It will run
everything on scheduled nightly runs, but only a subset on PRs (to reduce
time and variance due to short cases).

Also prints the job matrix in descending duration order, which
effectively makes GitHub actions schedule longest jobs first to reduce
total workflow latency.

Optimize runtime assertOn() checks (#7707) 
Combine consecutive assertOn() checks into one, and hoist past enclosing
'if' statements if possible. This enables combining a lot of them, which
can be worth 10% performance on some assertion heavy designs depending
on how the assertions are written.

Geza Lore 7b45b3ee8a Optimize string formatting runtime functions 
Add an overload that takes `const char*` format string. This avoids
having to construct/destruct a temporary `std::string` at the call site
when calling these functions with a string literal, which is fairly
common. This is worth 25% code size on some assertion heavy design.

Also use `std::string::clear()` instead of assigning an empty string
which is more efficient.

Optimize $sformatf into $sformat (#7701) 
Turn `x = $sformatf(...)` into `$sformat(x, ...)`. The former requires
checking and running a destructor for `x` at the call site, the later
does it in the callee VL_SFORMAT. This reduces the size of the call
site, which can be significant e.g. in the presence of many assertions.

Also added a rewrite of `$sformat(x, "const-string")` back into `x =
"const-string"` for the cases where the `$sformatf` would have been
folded into a constant string.

Optimize VL_SFORMAT when result is string (#7702) 
Omit unused bit width parameter. Emit rule is simple enough to change
and the unused parameter just bloats code size.

Optimize $sformat in V3Life (#7703) 
Treat AstSFormat as a special form of assignment in V3Life. This allows
eliminating earlier redundant assignments to strings when an $sformat
later sets the string. UVM has lot of these.

Optimize DPI import argument passing (#7704) 
Pass inputs to DPI import wrappers by reference (unless fits in a
