RPGLE devex improvements for built-in functions and procedures 🚀

[worksofliam]

I am here to share two major improvements to the RPGLE writing experience in VS Code today! This new functionality is available in vscode-rpgle 0.33.0.

Relevant built-in functions

When using the dot notation on variables/fields/subfields, you will now see applicable built-in functions. Inspired by the Golang LSP, we will show specific built-in functions based on the type of variable you are referencing. In this example (below), mytext is a string primitive, and since I started typing .scan it is showing me all built-in functions that start with scan.

This is more object-orientated, like showing member functions to a class, but when accepting a built-in function option off of a field, it will actually wrap the given field in the built-in function. See the video at the end of a full demo!

Signature information

For all used-defined procedures, prototypes and built-in functions, we will now show the signature for the given function. This means seeing type and documentation information for the current parameter while writing the call to the function.
