Fix numeric prims

[leonschoorl]

This fixes various issues with primitives on various number types. Some of it caused by changes in GHC, like the change from integer-gmp to ghc-bignum and the addition of sized versions of unboxed Int and unboxed Word. And some that were just never tested properly.

• blackboxes for GHC.Prim.c[lt]z*
• primitive evaluator for Int64 and Word64 primitives with GHC >= 9.4
• big negative Integer literals in evaluator
• VHDL rendering of Int32 literals with GHC >= 9.2
• don't generate out of range number literals
• VHDL blackbox for GHC.Num.Integer.integerTestBit#
• VHDL blackboxes for all signed multiplication
• (System)Verilog blackbox for Signed.fromInteger# now does the same as the VHDL one

For more details see the individual commits.

Still TODO:

• [X] Write a changelog entry (see changelog/README.md)
• [x] Check copyright notices are up to date in edited files

I'll squash/fixup the new commits later. But I've kept them separate for your re-reviewing pleasure.
