[third-party] Add a snapshot of Boost.Math 1.89 standalone (#141508)
This PR adds the code of Boost.Math as of version 1.89 into the
third-party directory, as discussed in a recent RFC [1].

The goal is for this code to be used as a back-end for the C++17
Math Special Functions.

As explained in third-paty/README.md, this code is cleared for
usage inside libc++ for the Math Special functions, however
the LLVM Foundation should be consulted before using this
code anywhere else in the LLVM project, due to the fact
that it is under the Boost Software License (as opposed
to the usual LLVM license). See the RFC [1] for more details.
