feature: specify the target evm version to solc for yul compilation

[danceratopz]

This PR:

• Adds an optional keyword argument to the Yul constructor that allows the user to specify the fork for which the code should be compiled for. This fixes evm version not passed to solc when compiling yul #135.
• Adds a --solc-bin command-line flag analogous to --evm-bin.
• Checks whether any forks (configured the command-line) don't supported by the configured solc binary. This may be done in the forks plugin, but perhaps undesirable as it would potentially force users to use a development version of solc to run fill with dev forks.

Note, after changing the behavior so that Yul gets compiled with the test's current fork parameter value: tests/security/test_selfdestruct_balance_bug.py fails if compiled with Constantinople or Shanghai. Shanghai can be explained: This is just because solc refuses to compile contracts with SELFDESTRUCT. I didn't understand why the code doesn't compile for Constantinople yet. We don't need to fix this in the scope of this PR, imo, but we should make a ticket to not forget. This is currently avoided by applying @pytest.mark.compile_yul_with("Merge").

Looks good! :)

Only two minor comments that would not affect the tests.
