[PATCH 20/79] [Backport to 15][DebugInfo] Add new Source Languages table used in DebugCompilationUnit  (#1854)

This extended source language table is used by DebugCompilationUnit instruction when the extension is enabled. It enables support for more languages than exists in a core specification.
Spec: KhronosGroup/SPIRV-Registry#186

Enabling of Fortran language also allowed to fix FortranArray test that was originally XFAIL-ed in 9e234d9.
