[PATCH v1 1/4] app/test-pmd-api: Add C++ Compiler

[ohilyard@iol.unh.edu]

From: Owen Hilyard <ohilyard@iol.unh.edu>

Adds a C++ compiler to the project, which is currently enabled by
default for ease of testing. Meson currently lacks a way to try to get a
compiler, and failing to find a compiler for a language always causes a
hard error, so this is the only workable approach.
