  MSVC is the only compiler that can produce usable shared libraries for
DPDK on Windows because of the use of exported TLS variables.

Disable building of shared libraries with LLVM and MinGW so that
remaining __declspec macros needed for the functional libraries built by
MSVC can be used without triggering errors in LLVM and MinGW builds.

For Windows only install the default_library type to avoid confusion.
Windows builds cannot build both shared and static in a single pass so
install only the functional variant

MSVC does not guarantee any kind of compatibility for static libraries so
they should not be packaged and instead they should be rebuilt along with
the application using the same version of the compiler & linker.  Because
of this we have chosen to build only one library type at a time instead of
compiling twice to produce both types in a single pass.

  * condense library, target and toolchain type logic determining values for
    is_shared_enabled,install_{static,shared} values.
  * define empty shared_dep object to allow unconditional evaluation of shared
    variables even when is_shared_enabled is false.
  * use default_library() string to determine deps for chkincs.
