Add GHDL as plugin to Yosys

[NikLeberg]

Add the ghdl-yosys-plugin to Yosys.

For reasoning, see SpinalHDL/SpinalHDL#1429.

This also builds GHDL from source instead of pulling from apt.

I tested this in my own projects over at NikLeberg/container_builder. There I did update all the build arguments to the latest versions though:

UBUNTU_VERSION=24.04
YOSYS_VERSION=yosys-0.41
SOLVERS_PATH=snapshot-20240212/ubuntu-22.04-X64-bin.zip
BOOLECTOR_VERSION=3.2.3
SYMBIYOSYS_VERSION=yosys-0.41
GHDL_VERSION=v4.1.0
GHDL_PLUGIN_VERSION=0c4740a
MILL_VERSION=0.11.7

Not sure if this is required or wished for.

Nice, it would be worthful to have this function after the yosys+ghdl backend is merged.
Due to SpinalHDL's CI workflow use the image from this repo's master release, we should release it carefully.
