runtime: query thread stack size from OS on Windows
Currently, on Windows, the thread stack size is set or assumed in many
different places. In non-cgo binaries, both the Go linker and the
runtime have a copy of the stack size, the Go linker sets the size of
the main thread stack, and the runtime sets the size of other thread
stacks. In cgo binaries, the external linker sets the main thread
stack size, the runtime assumes the size of the main thread stack will
be the same as used by the Go linker, and the cgo entry code assumes
the same.
Furthermore, users can change the main thread stack size using
editbin, so the runtime doesn't even really know what size it is, and
user C code can create threads with unknown thread stack sizes, which
we also assume have the same default stack size.
This is all a mess.
Fix the corner cases of this and the duplication of knowledge between
the linker and the runtime by querying the OS for the stack bounds
during thread setup. Furthermore, we unify all of this into just
runtime.minit for both cgo and non-cgo binaries and for the main
thread, other runtime-created threads, and C-created threads.
Updates #20975.
