Change javax.tools.ToolProvider methods calls to static

org.openrewrite.java.migrate.RemovedToolProviderConstructor

The recipe converts javax.tools.ToolProvider getSystemJavaCompiler(), javax.tools.ToolProvider getSystemDocumentationTool() and javax.tools.ToolProvider getSystemToolClassLoader() to static methods.
