Win32: PCRE2 Unicode support with MSVC.

Unicode support in PCRE2 is enabled by default on configure/cmake side
by defining SUPPORT_UNICODE.  Previously, this macro was not defined
when compiling directly PCRE2 sources for Windows with MSVC.

In particular, this change allows to specify Unicode properties, such as
\P, \p, or \X, as caught by http_server_name.t adjusted to run on Windows:

nginx: [emerg] pcre2_compile() failed: this version of PCRE2 does not have
support for \P, \p, or \X
