Fix intellisense on Windows

[enginelesscc]

__INTELLISENSE__ is 1 on vs2022 and clang, causing FMT_HAS_INCLUDE, FMT_USE_FCNTL, etc to be 0.
That results in VS and VSCode having a lot of linter errors while code compiles just fine.

Removing && !defined(__INTELLISENSE__) fixes these problems.

a lot of linter errors

    using variant_test = std::variant<std::monostate, std::string>;
    variant_test default_;
    variant_test string_ = "World";

    fmt::print("Hello, {}!\n", default_);
    fmt::print("Hello, {}!\n", string_);
}

Build: successful
Console output:

Hello, variant(monostate)!
Hello, variant("World")!

test.log:

test : 1662402400

Example intellisense output (VSCode, clang 14.0.6):

Reason for errors:

• Lack of includes in fmt/std.h (Missing FMT_HAS_INCLUDE)
• Lack of FMT_USE_FCNTL in fmt/os.h (Missing FMT_HAS_INCLUDE)
