feat(eslint-plugin): [naming-convention] add modifiers exported, global, and destructured modifiers - add selectors classProperty, objectLiteralProperty, typeProperty, classMethod, objectLiteralMethod, typeMethod

Fixes #2239
Fixes #2512
Fixes #2318
Fixes #1477
Closes #2691

Big update to add a bunch of stuff.
I couldn't be bothered splitting this out into separate PRs.

Adds the following modifiers:

• exported - matches anything that is exported from the module.
• global - matches a variable/function declared in the top-level scope.
• destructured - matches a variable declared via an object destructuring pattern (const {x, ignored: y, z = 2}).

Adds the following selectors (self explanatory - just breaking the selectors up):

• classProperty
• objectLiteralProperty
• typeProperty
• classMethod
• objectLiteralMethod
• typeMethod

Converts

• property to a meta selector for classProperty, objectLiteralProperty, typeProperty
• method to a meta selector for classMethod, objectLiteralMethod, typeMethod

TODO

• add example for disabling naming convention for destructured variables.
• fix destructured applying to names that aren't directly destructured names:

const {
  a,     // a should be matched
  b = 2, // b should be matched
  c: d,  // c should be ignored, d should not be matched
  e: f = 3, // e should be ignored, f should not not be matched
};
