Server emits a telemetry event for initialization

Please refer to `USAGE_DATA.md` for a full list of data collected.

Add `xml.telemetry.enable` to control if telemetry events are sent.

+# Telemetry data collection
+
+If `xml.telemetry.enabled` is set to `true`, LemMinX emits telemetry events.
+These events can be collected by the LSP client program.
+
+When telemetry events are enabled, the following information is emitted when the language server starts:
+
+ * JVM information:
+ * Whether LemMinX is being run with Java or as a GraalVM native image (binary)
+ * The name of the vm (`java.vm.name`)
+ * The name of the runtime (`java.runtime.name`)
+ * The version of the JVM (`java.version`)
+ * The free, total, and max VM memory
+ * Does NOT include the `JAVA_HOME` environment variable for privacy reasons
+ * Version information:
+ * The Maven version number
+ * The branch of the build
+ * The short form of the commit id
+ * The short form of the commit message
+
+Currently, the startup event is the only telemetry event that is emitted.
