feat(database): add SQL living documentation support

This commit adds support for generating living documentation for SQL files. It includes a new class `SqlLivingDocumentationProvider` that implements the `LivingDocumentation` interface. The class provides methods for generating documentation comments, finding documentation targets, and updating documentation. Additionally, a new XML file `cc.unitmesh.database.xml` is added to configure the plugin and specify the implementation class for SQL living documentation. The build.gradle.kts file is modified to include the `com.intellij.database` plugin as a dependency for the `exts:database` project. Finally, the `BasedDocumentationIntention.kt` file is modified to remove the `getClosestNamedElement` method and update the `getClosestToCaretNamedElement` method accordingly.
