Pull Request resolved: https://github.com/facebookexperimental/eden/pull/107

Summary

* Add EdenFS builds on external CI now EdenSCM is good

* Mac builds on github actions by using brew for system dependencies

To make this work had to fix some path ordering issues with install directories for Linux and Mac, and generalise the homebrew path fixups we were doing for bison to all the used homebrew packages.

Previously Installed packages were being added after system paths, so our own installed thing might be ignored. On github these meant system python 3.9 was being used for hg tests rather than our specified 3.8 (this showed we have some test fails on python 3.9 with "SystemError: deallocated bytearray object has exported buffers", that are beyond the scope of this diff to fix)

Also needed to include the getdeps generated python into the generated edenscmdeps3.zip archive setup.py produces otherwise EdenFS tests failed to import thrift.Thrift

Eden tests are hanging when run externally about half way through, so disable them on github actions for now as this PR is already fairly large. They work when run locally on an internal devserver, so probably some bit of environment necessary is not defined in the test runner

Summary:
In a way which also happens to improve build speed.

It turns out that the bulk of the improvement comes from removing the use of `std::is_nothrow_move_constructible` since it may internally have a `std::declval` in there. But that's not the only source of improvements.

Summary:
For global variables with nontrivial destructors, the compiler inserts calls to `atexit` to destroy the variables at shutdown time. For global variables with trivial destructors, the compiler elides such calls. Revise `Indestructible` to have a trivial destructor.

Some compilers optimize further and remove such calls even for some nontrivial destructors, but not all do so.

Also remove move-construction and move-assignment. And remove actual `constexpr`-constructibility since `::new` is not a constant expression.
