opt_expr: Fix #4590
...
If all the (non-select) inputs of a `$_MUX{4,8,16}_` are undefined, replace it, just like we do for `$mux` and `$_MUX_`.
Add `tests/opt/opt_expr_mux_undef.ys` to verify this.
This doesn't do any const folding on the wide muxes, or shrinking to less wide muxes. It only handles the case where all inputs are 'x and the mux can be completely removed.

Liberty file caching with new libcache command
...
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.

simplify: Skip AST_PRIMITIVE in AST_CELLARRAY
...
Otherwise the `AST_PRIMITIVE` simplifies to the corresponding function and is no longer caught by the check for `AST_PRIMITIVE`s, raising an assertion error instead of an input error.
Add bug4785.ys to tests/verilog to demonstrate.

select: Fix -none and -clear
...
If the selection stack only has one element (which it normally does), then
`design->pop_selection()` automatically resets to the default full selection.
This is a problem for `select [-none | -clear]` which were trying to replace the
current selection, but because the pop added an extra element when the `execute`
returned, the extra selection (the one we actually wanted) gets popped too. So
instead, reassign `design->selection()` in the same way as if we called `select
[selection]`.
Also adds selection stack tests, and removes the accidentally-committed
`boxes_dummy.ys`.
