* OpenFOAM: rationalize architecture options

- older versions of OpenFOAM had WM_ARCH_OPTION to choose a 32-bit
  build on 64-bit architectures. This is not exactly relevant anymore
  and has now been largely removed from OpenFOAM.

- simultaneously the newest version of OpenFOAM has rationalized the
  handling of special settings for KNL by rolling these into the
  compiler options. We now do the same thing here in spack.

  1. Reuse the internal variable arch_option to convey processor-specific
     optimizations and add these into the C++OPT=... statement.
  2. Drop spack support for configuring a 32-bit build on 64-bit
     hardware.

These changes can also be applied to older OpenFOAM versions, and to
various OpenFOAM forks without issue.

* update openfoam versions. New release 1906, patched 1812 version.

Some of the fonts now included in font-util need mkfontdir to build.

pkgconfig is the correct virtual dependency.

Commit ea3e1521 removed version
1.9.7rc2, making the patch for gcc@9 obsolete.

ncl does not build with newer versions of gdal (or rather proj). This
also needs a small change to gdal, otherwise we end up with both proj@5
and proj@6 in the spec.

- Separate `yaml-cpp` tests into variant
- Make conflict between `yaml-cpp` tests and `libc++` explicit

* phist can't be compiled with gcc older than 4.9.2

* fmt: Add cxxstd variant, plus cmake/c++ patches

Spack supported versions of fmt default to C++11 for versions
less than 5, C++14 greater than 5, with fmt implementing
fallbacks to whatever compiler supports.

To give better ABI compatibility and use of newer standards, provide
a `cxxstd` variant defaulting to 11 with 98-17 options. Use cmake_args
to set CMAKE_CXX_STANDARD as appropriate, plus use of `FMT_USE_CPP11`
option for C++98 builds. Use `conflicts` to disable use of certain
standards in versions that don't support, or fail the build, with
those standards.

Add patches to unify use of `CMAKE_CXX_STANDARD` in 3.0 versions,
remove hard-coding of compiler flags in `fmt-config.cmake`, and
prevent use of C++11 features in 4.1.0 when in supported C++98
mode.

Default to not building documents as no dependency on Doxygen is
yet present, and they are not part of the "all" build.

* Use CMake to enforce C++ standard support

Fail configure step if fmt tries to build with a cxxstd variant
not supported by the compiler (or known to CMake).

* fmt: New version 5.3.0

The issue with locking in a multithreaded environment has been
fixed/worked around in version 3.3.

Also, add bzip2 and lzo variants.

Fixes #11816

Allow packages to refer to non-expanded downloads (e.g. a single
script) using Stage.archive_file. This addresses a regression from
#11688 and adds a unit test for it.
