Revert r364332 "[scudo][standalone] Introduce the C & C++ wrappers"

Makes the build fail with e.g.

  llvm/projects/compiler-rt/lib/scudo/standalone/wrappers_c.inc:20:68: error:
  declaration of 'void* calloc(size_t, size_t)' has a different exception
  specifier
   INTERFACE WEAK void *SCUDO_PREFIX(calloc)(size_t nmemb, size_t size) {
                                                                      ^

See llvm-commits thread.

> Summary:
> This CL adds C & C++ wrappers and associated tests. Those use default
> configurations for a Scudo combined allocator that will likely be
> tweaked in the future.
>
> This is the final CL required to have a functional C & C++ allocator
> based on Scudo.
>
> The structure I have chosen is to define the core C allocation
> primitives in an `.inc` file that can be customized through defines.
> This allows to easily have 2 (or more) sets of wrappers backed by
> different combined allocators, as demonstrated by the `Bionic`
> wrappers: one set for the "default" allocator, one set for the "svelte"
> allocator.
>
> Currently all the tests added have been gtests, but I am planning to
> add some more lit tests as well.
