fix(no-v-html): add CallExpression support to ignorePattern option (#2949)

This commit extends the `ignorePattern` option to support function call expressions
like `$sanitize(test)`, not just simple variable identifiers like `htmlSafe`.

Changes:
- Add new `shouldIgnore()` helper function that handles both Identifier and
  CallExpression expression types
- For Identifiers, use the `name` property directly for optimal performance
- For CallExpressions and other expression types, use `sourceCode.getText()`
  to get the full expression text
- Update the visitor to pass `sourceCode` to the new helper function

This allows users to configure patterns like `^\$sanitize\(` to match function
call expressions where the function name matches the pattern.

Tests:
- Add test case for CallExpression matching with ignorePattern `^\$sanitize\(`
- All existing tests continue to pass
