make CMake's version config file architecture-independent

[uhoreg]

Fixes #1697. In short, CMake's write_basic_package_version_file by default creates a file that checks whether it is being called on a 32- or 64-bit architecture, and will fail if it is called on a different bit size than what it was built on, even though that doesn't affect the JSON library, since it is header-only. This replaces the automatically-generated file with a file that checks the version requirement, but does not check the word size. (It is essentially CMake's file, but with the word size check removed.)

Coverage remained the same at 100.0% when pulling cade804 on uhoreg:cmake_arch_indep into 06ccd43 on nlohmann:develop.

@uhoreg @nlohmann Is that good to go? I think I'm seeing some fallout of not having that in #1780.

Edit: No, I just had to adapt to new cmake flags wanting the architecture separately.

@nlohmann can you re-open this please (or even better, merge it. ;) )

Sorry for the long delay. It would be great if you could address my comments, then this issue would be finally fixed.

[uhoreg]

I've added comments as requested.

Looks good to me.
