refactor: adapt isContext cheatcode

[agostbiro]

Foundry has an isContext cheatcode that tells you which forge command was used to execute the Solidity code (e.g. forge test or forge coverage or forge script).

I adapted the isContext cheatcode for EDR by renaming the context enum from ForgeContext to ExecutionContext and removed the scripting related variants.

The Foundry code assumes that Solidity code is ran via the forge CLI and that the execution context is set based on the subcommand once per process. This doesn't make sense for us, since EDR provides Solidity tests as a library, so I changed this to getting the execution context as a config value in the cheatcode implementation.

I changed the representation of the execution context in the Rust code. I split the previous ForgeContext enum into two enums as it was previously used as both as an argument from Solidity where it can have five variants and as a config value where it can only have four variants (TestGroup doesn't make sense as a config value).

I also removed the PartialEq implementation for the previous ForgeContext and inlined its logic in the cheatcode as the PartialEq implementation wasn't symmetric (Test == TestGroup, but TestGroup != Test) which can be a source of subtle bugs.
