[PATCH v2 1/6] Move mingw_* declarations to the mingw folder

[Evgeny Karpov <Evgeny.Karpov@microsoft.com>]

This patch refactors recent changes to move mingw-related
functionality to the mingw folder. More renamings to the mingw_
prefix will be done in follow-up commits.

This is the first commit in the second patch series to add DLL
import/export implementation to AArch64.

Coauthors: Zac Walker <zacwalker@microsoft.com>,
Mark Harmstone <mark@harmstone.com>  and
Ron Riddle <ron.riddle@microsoft.com>

Refactored, prepared, and validated by
Radek Barton <radek.barton@microsoft.com> and
Evgeny Karpov <evgeny.karpov@microsoft.com>
