Change "extract variable" to allow extracting literals, not just expressions.

[camercu]

Suppose I had a statement like so:

let result = some_complicated_computation(arg1, arg2, arg3, "annoyingly long literal of text");

I'd like to be able to put my cursor inside the str literal (or a numeric literal) and have the option to run a refactoring code action to extract the literal into a variable. The result of running this on the previous example would be:

let var_name = "annoyingly long literal of text";
let result = some_complicated_computation(arg1, arg2, arg3, var_name);

The refactoring can improve readability or set the code up for further refactorings (like moving the variable to a parameter/field).

Currently when I try to do this (in VSCode), I get no such option.

#15809 should resolve this, what's your RA version?

Ha, after reloading my vscode it works... removing my foot from my mouth now.

For reference, I'm running:

rust-analyzer 1.75.0 (82e1608d 2023-12-21) (binary)

with VSCode extension version v0.3.1799.

You guys are an amazing team that's building a fantastic program. Thanks for what you do!
