build-openssl.bat: keep OpenSSL 3 engine binaries

Prior to this change copying the OpenSSL 3 engine binaries failed
because 'engines-1_1' (OpenSSL 1.1.x folder name) was erroneously used
instead of 'engines-3'. The OpenSSL 3 builds would complete successfully
but without the engine binaries.

projects: Update VS projects for OpenSSL 1.1.x

- Update VS project templates to use the OpenSSL lib names and include
directories for OpenSSL 1.1.x.

This change means the VS project files will now build only with OpenSSL
1.1.x when an OpenSSL configuration is chosen. Prior to this change the
project files built only with OpenSSL 1.0.x (end-of-life) when an
OpenSSL configuration was chosen.

The template changes in this commit were made by script:

libeay32.lib => libcrypto.lib
ssleay32.lib => libssl.lib
..\..\..\..\..\openssl\inc32 => ..\..\..\..\..\openssl\include

And since the output directory now contains the includes it's prepended:
..\..\..\..\..\openssl\build\Win{32,64}\VC{6..15}\{DLL,LIB}
{Debug,Release}\include

- Change build-openssl.bat to copy the build's include directory to the
output directory (as seen above).

Each build has its own opensslconf.h which is different so we can't just
include the source include directory any longer.

Note the include directory in the output directory is a full copy from
the build so technically we don't need to include the OpenSSL source
include directory in the template. However, I left it last in case the
user made a custom OpenSSL build using the old method which would put
opensslconf in the OpenSSL source include directory.

- Change build-openssl.bat to use a temporary install directory that is
different from the temporary build directory.

For OpenSSL 1.1.x the temporary paths must be separate not a descendant
of the other, otherwise pdb files will be lost between builds.
