Conda-forge.github.io: Add more relevant information in the 'compilers' section

[ForgottenProgramme]

https://conda-forge.org/docs/maintainer/knowledge_base.html#compilers

Currently, the 'Compilers' section is incomplete and unhelpful.

Refer: https://github.com/conda-forge/conda-forge.github.io/issues/893#issuecomment-634881487

The link mentioned in the comment by @isuruf doesn't exist as conda-forge doesn't use wiki anymore.
(https://github.com/conda-forge/conda-forge.github.io/issues/893#issuecomment-634915638)

Suggested Solution:

The following list should be added to the compiler section:

Activation recipes
1.GCC - https://github.com/conda-forge/ctng-compiler-activation-feedstock

1. Clang, OSX - https://github.com/conda-forge/clang-compiler-activation-feedstock
2. gfortran, OSX - https://github.com/conda-forge/gfortran_osx-64-feedstock

Implementation packages

1. GCC - https://github.com/conda-forge/ctng-compilers-feedstock
2. gfortran, OSX - https://github.com/conda-forge/gfortran_impl_osx-64-feedstock
3. clang
   https://github.com/conda-forge/llvmdev-feedstock
   https://github.com/conda-forge/libcxx-feedstock
   https://github.com/conda-forge/clangdev-feedstock
   https://github.com/conda-forge/openmp-feedstock
   https://github.com/conda-forge/tapi-feedstock

1. OSX - https://github.com/conda-forge/cctools-and-ld64-feedstock

Suggestions invited.

@viniciusdc , I'm taking this up.

The wiki was disabled, which is why the link didn't work. Reenabled it so we can pull that information. Though I think we are trying to not use the wiki in the future. So we may want to disable that again after this is done

Windows also reuses Visual Studio with some activation scripts

Also we have a CUDA compiler for GPU code

I believe there are Rust and Go compilers as well. Not sure if there are any other languages I'm missing

[ForgottenProgramme]

Alright,
so we add information about the CUDA compilers and then check for Rust and Go.

yup, @jakirkham I copied the info there and passed it to @ForgottenProgramme as a source for this issue body. I will close the wiki again.

@jakirkham Maybe we could use https://github.com/conda-forge/conda-forge-pinning-feedstock/blob/master/recipe/conda_build_config.yaml to auto update this information in the future, what do you think?

Maybe. @CJ-Wright @beckermr @isuruf do you have thoughts on this?

[hitblunders]

@ForgottenProgramme are you working on this?
