tgt-vlog95: Find the original signal when a port connection is cast.

Don't mislabel signals as ports when casting port connections.
...
The original signal should retain the port type. Moving it to the cast
signal was confusing the vlog95 and stub targets.

Fix bitmask merging in synthesis.
...
A conditional clause that doesn't drive any bits of a particular nexus
should not affect the bitmask generated for that nexus. The completely
undriven case is handled by the enable signal.

vhdlpp: Handle limited-length strings in reports.
...
Currently limited-length strings (e.g. string(1 to 4)) are
emulated using 2D array of bits (e.g. bit [1:4][7:0]).
Because of that, ivl treats them as standard vectors and
$display() does not show them as strings. Now, they are
wrapped with $sformatf("%s", ..) to fix it.
