Original PR: https://github.com/arvidn/libtorrent/pull/4091

* Update ci.baseline.txt:
- fail libgo:* due to use the removed class from Boost.Context 1.72.0 (reported issue https://github.com/yyzybb537/libgo/issues/214)
- pass boost-context:arm64-windows
- fix typo

* Folly only supports the x64 architecture

* fail boost-coroutine:arm64-windows=fail and boost-fiber:arm64-windows=fail because they use fcontext_t from Boost.Context which is not implemented for Windows on ARM64 (reported issue https://github.com/boostorg/context/issues/130)
