MSVC's `link.exe` automatically finds `__cdecl` C functions (which are
decorated with a leading underscore by the compiler) when they are
mentioned in a `.def` file without the leading underscore. This is an
[under-documented feature][1] of MSVC's `link.exe`. C++Builder's
`ilink32.exe` doesn't do this, and thus needs the name-translation in
the `.def` file. Then `implib.exe` needs to be told to re-add it.
(The Clang-based `bcc32c.exe` doesn't implement the [`-vu` or `-u-`][2]
options to skip adding the leading underscore to `__cdecl` C function
names, so this is the only way to have things work with non-underscored
export names in the DLLs.)

Also silence linker warnings on duplicate symbols and ensure that error-
case cleanup in link rules work in C++Builder's `make.exe`.

In OpenSSL 1.1.1, VC-WIN64I and VC-WIN64A have a 'multilib' attribute
set, which affect the names of the produced libcrypto and libssl DLLs.
This restores that for OpenSSL 3.0.
Fixes#13659

Add platform::Windows, which is a generic Windows module, and
platform::Windows::MSVC, which is a module specifically for MS Visual
C.
This reworks Configurations/windows-makeffile.tmpl to work out product
names in platform::Windows. Something to be noted is that the new
functionality ignores the *_extension config attributes, as they were
never used.
