Add pkgconfig file in the sources

Hi

is possible add a pkgconfig file in the sources, like vulkan-loader and spirv-tools?

Generating pkg-config metadata would be a useful way to codify what is necessary to link to each of the API entry points provided by glslang. Sections of the API that are identifiably different (like the C++ class interface vs. the C functional interface, or any features that pull in additional dependencies) might benefit from separate .pc files.

At the moment, users of glslang need to know the names of all the static libraries, as well as the dependencies between them, and the fact that some (all?) need -lpthread on platforms that have it. pkg-config metadata could reduce this to something like:

# CMake
pkg_check_modules (GLSLANG REQUIRED glslang>=7.10)
# ... compile with ${GLSLANG_INCLUDEDIR}, link with ${GLSLANG_LIBRARIES}

# or Meson
glslang = dependency('glslang', version : '>=7.10')
executable(..., dependencies : [glslang])

# or Autotools
PKG_CHECK_MODULES([GLSLANG], [glslang >= 7.10])
# ... compile with ${GLSLANG_CFLAGS}, link with ${GLSLANG_LIBS}

# or plain Make/shell
c++ -oexample example.cpp $(pkg-config --cflags --libs "glslang >= 7.10")

The Fedora packaging at https://src.fedoraproject.org/rpms/glslang/tree/master seems to have patches for this, which have also been applied in Debian.
