Check for supported tool versions
Define supported tool versions in tool_requirements.py, and check them
in a fusesoc run. If an unsupported tool version is found, fusesoc
outputs an error like this:
```
$ fusesoc --cores-root ../../ run --target=lint lowrisc:ip:aes
INFO: Preparing lowrisc:constants:top_pkg:0
INFO: Preparing lowrisc:lint:comportable:0.1
...
INFO: Preparing lowrisc:tool:check_tool_requirements:0.1
INFO: Preparing lowrisc:lint:common:0.1
...
INFO: Preparing lowrisc:ip:aes:0.5
ERROR: verilator is too old: found version 4.016, need at least 4.028
ERROR: Tool requirements not fulfilled. Please update the tools and retry.
ERROR: Failed to build lowrisc:ip:aes:0.5 : pre_build script \
'check_tool_requirements' exited with error code 1
```
The only version checked at this point is Verilator, which is set to
version 4.028, the first version to support wildcard matching for
`lint_off` rules.
The whole infrastructure has been created by @imphil in the Ibex
repository (see lowRISC/Ibex#604). This commit just copies the
framework over to OpenTitan.
