support abi.encodeCall

[plotchy]

abi.encodeCall is not supported as a SolidityFunction/SolidityCall. This adds support

@0xalpharush / @montyly If you have time, can you help explain how to set up an ast_parsing test to me? I plan to add tests, but could use a little guidance

[0xalpharush]

I would modify units_and_global_variables-0.8.12.sol . If necessary, create another test case in tests/ast-parsing with a newer version of Solidity (not sure if this bug is relevant).

For each test case, we store a zip file of the compilation e.g. units_and_global_variables-0.8.0.sol-0.8.12-compact.zip.

For existing test cases that are modified, it must be deleted and regenerated.

For new test cases the zip file needs to be created for the first time. In addition, new test cases must be registered here with the file name and which solidity versions it should be tested against.

Command to generate zip for test:

python ./tests/test_ast_parsing.py --compile

Then, you can generate the json file of slither's output:

python ./tests/test_ast_parsing.py --compile

You can copy commands from here in your local environment https://github.com/crytic/slither/blob/master/CONTRIBUTING.md#parser-tests

Here's what a similar PR ended up looking like #1086. Lmk if you have other questions or need clarification.

Thanks @plotchy
