Benchmark for the Valum framework (#2762)

* Benchmark for the Valum framework

Minimally implements the '/plaintext' and '/json' endpoints.

JSON-based benchmarks are implemented with 'json-glib-1.0'.

Include setup for the following tools:

 - meson
 - ninja
 - vala

* Use a specific version of Meson for reproducibility

* Add a README.md for describing Valum

* valum: Use 'GLib' instead of 'VSGI' for the platform

+# Valum Benchmarking Test
+
+[Valum](http://valum-framework.org/) is a Web micro-framework written in Vala
+and leveraged by the whole GLib ecosystem.
+
+## JSON Encoding Test
+
+Uses [JSON-GLib](https://wiki.gnome.org/Projects/JsonGlib) for building and
+serializing the payload.
+
+## Test URLs
+
+### JSON Encoding Test
+
+http://localhost:3003/json

+### Plaintext Test
