Add testbench targets on top-level
The testbenches live in their own Makefiles under
hw/application_fpga/core/*/toolruns (except picorv32). Let's add a
top-level target to build and run them.

In order to run core testbenches, use

  cd hw/application_fpga
  make tb

or if using Podman:

  cd contrib
  make run-tb

to run the same target in a container.

fw: Change ASLR name in MMIO
Use _RAM_ADDR_RAND instead of _RAM_ASLR since this is not OS-level
ASLR we're talking about. It's address randomization as seen from
outside of the CPU, not from the process running inside it. Ordinary
ASLR is visible from the CPU.

fw: Change license for use with qemu
This file is also included in at least qemu (GPL-2.0-or-later) besides
tillitis-key1 (GPL-2.0-only) and tkey-libs (GPL-2.0-only) so it's
licensed as GPL v2 or later even if the rest of the project is -only.

fw: Change memory constants to defines
Instead of putting  memory constant into an enum we use defines.

Use the direct memory address instead of ORing constants together to
compute the address.

An enum in ISO C is a signed int. Some of are memory addresses are to
large to fit in a signed int. This is not a problem since we're not
using ISO C (-std=gnu99) but it doesn't look very nice if you turn on
pedantic warnings. Also, if someone would use another compiler which
at least supports the inline assembly we use, but possible not other
GNU extensions, things would probably break.

Use pedantic warnings
Use pedantic warnings but still allow inline assembly, so turn off
language-extension-token warnings.

fw: Remove unusued forever_redflash()
Since we now use assert() and feed the CPU an unimplemented
instruction we have no need for this.
