pgsql: More MSVC build fixes: * New versions of OpenSSL come with

Log Message:
-----------
More MSVC build fixes:

* New versions of OpenSSL come with proper debug versions, and use
suffixed names on the LIBs for that. Adapts library handling to deal
with that.

* Fixes error where it incorrectly enabled Kerberos based on NLS
configuration instead of Kerberos configuration

* Specifies path of perl in config, instead of using current one.
Required when using a 64-bit perl normally, but want to build pl/perl
against 32-bit one (required)

* Fix so pgevent generates win32ver.rc automatically
