Allow disabling `Hint is not whitelisted` error for certain files

[Arkadiusz]

As a Protostar user, I want to disable checking if hint is whitelisted for my test files so that Protostar's cheatcodes aren't highlighted as errors.

{
  "cairols.filesUsingCustomHints": [
    "./tests/**/",
  ]
}

I would also be very interested in this update

If anyone is interested in doing a PR, here are the relevant sections of code:

• where the compiler is called for the current file
• settings interface
• settings defaults
• settings definitions for VS Code extension

I would like to work on this one as it's important for us as a protostar team to let users use protostar with cairo-ls.

Proposal, consistent with starknet interface:

"cairols.disableHintValidation": {
	"scope": "resource",
	"type": "string",
	"description": "Disables hint validation for "
},
