This PR implements the extension framework and adds the load extension [path] statement to allow the user to load an extension in kuzu.
Currently, extensions are not supported on windows platform due to a linking error.

@ray6080 should check the change related to fileSystems

[ray6080]

Can we add tests for these exceptions?

[acquamarin]

The error message is system dependent, we should improve our testing framework so that it allows fuzzy match error strings.

[ray6080]

Okay. Can you open an issue on this? We should improve the testing framework for this.
