feat(tools): improve solc error messages about execution-spec-tests HOT 1 CLOSED

• The last few versions of solc are supported (currently 0.8.20, 0.8.21, and custom builds of upcoming 0.8.22).
• Test cases do not specify which version of solc is required to compile the yul defined within the test.

The following error messages are provided:

1. solc not found

   fill tests/homestead/yul/test_yul_example.py -x --solc-bin=/home/dtopz/bin/solc-0.123.0
