rustc: Switch defaults from libgreen to libnative #12833

  1. rustc: Switch defaults from libgreen to libnative 

    The compiler will no longer inject libgreen as the default runtime for rust
programs, this commit switches it over to libnative by default. Now that
libnative has baked for some time, it is ready enough to start getting more
serious usage as the default runtime for rustc generated binaries.

We've found that there isn't really a correct decision in choosing a 1:1 or M:N
runtime as a default for all applications, but it seems that a larger number of
programs today would work more reasonable with a native default rather than a
green default.

With this commit come a number of bugfixes:

* The main native task is now named "<main>"
* The main native task has the stack bounds set up properly
* #[no_uv] was renamed to #[no_start]
* The core-run-destroy test was rewritten for both libnative and libgreen and
  one of the tests was modified to be more robust.
* The process-detach test was locked to libgreen because it uses signal handling

  2. rand: Rewrite OsRng in Rust for windows 

    This removes even more rust_builtin.c code, and allows us to more gracefully
handle errors (not a process panic, but a task failure).

  3. rand: Fix a bug acquiring a context on windows 

    The details can be found in the comment I wrote on the block in question, but
the gist of it is that our usage of the TIB for a stack limit was causing
CryptAcquireContext to fail, so we temporarily get around it by setting the
stack limit to 0.
