[Meson][Windows] detect MSVC usage

[UnixY2K]

previous check tested for compiler ID in meson, detection of an specific MSVC macro is preferred so it works in any compiler that includes the MSVC stdlib.

I noticed this error while trying to compile the 0.11.0 version

• changes the compiler check to macro check _MSC_VER which is an Microsoft specific macro
• changes the current defined version to 0.11.1, previous was 0.11.0

Wouldn't it be better to just remove that whole condition and add a default_options: ['cpp_std=c++11'] parameter to the project definition?

the issue is that MSVC stdlib is not fully C++11 compliant, so compilation will fail in Windows unless C++14 is used.

I set the std by default to C++11 and increased the meson version as I noticed some warnings with the new macro check, any other platform will just use C++11 by default.
