Add A reference to the SQL symbol type definer

[xterao]

Enables you to jump from a bind variable symbol to its definition by using Ctrl+click.
The target is Dao method argument parameters, class properties, and static property call classes.

Pull Request Overview

This PR introduces a reference jump feature for SQL symbols in the IntelliJ plugin, enabling Ctrl+click functionality from SQL bind variables to their corresponding definitions in DAO methods, class properties, or static fields. Key changes include a method renaming in the test suite, various updates to reference provider implementations to use new language constructs (e.g. SqlElIdExpr instead of SqlElPrimaryExpr), and adjustments in completion and inspection logic based on improved type checking.

• The method rename from 'addResourceFile' to 'addResourceEmptyFile' improves clarity; please verify that all test invocations are updated accordingly to avoid mismatches.

fun addResourceEmptyFile(vararg sqlFileNames: String) {

• Using PsiTreeUtil to retrieve the parent of a static element enhances robustness; please ensure that the source variable (staticDirection) is consistently defined and that the intended element is always targeted.

val classParent = PsiTreeUtil.getParentOfType(staticDirection, SqlElClass::class.java)

• The updated condition relies on checking the elementType instead of an instanceof check; confirm that this condition accurately identifies all relevant identifier cases without inadvertently filtering out valid references.

if (element.elementType == SqlTypes.EL_IDENTIFIER && element.prevSibling?.elementType != SqlTypes.DOT) {
