Support user defined value types.

See original GitHub issue

When using user defined value types (available since 0.8.8) the ast-dereferencer fails.

Compiling 111 files with 0.8.10
An unexpected error occurred:

error Command failed with exit code 1.

Apparently, using this contract replicated the issue.

Simple contract to reproduce the current error and test support:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.9;

contract UserDefinedValueType {
    type Timestamp is uint64;
}

Note: As mentioned in https://github.com/OpenZeppelin/openzeppelin-upgrades/issues/438 we need to be careful with Solidity 0.8.8 because it has buggy storage layout rules, they were fixed in 0.8.9. We should probably reject 0.8.8.
