Add missing headers and std qualification, use std::numeric_limits in…

[YexuanXiao]

…stead of macros, and use std::memcpy/std::swprintf instead of the non-standard memcpy_s/swprintf_s

memcpy_s and swprintf_s are not in the C++ standard, therefore they are not exported by std or std.compat. Other declarations are either exported by std.compat or become available due to the global module fragment (this is unstable unless all required headers are explicitly included). Ideally, only the module std should be used.

Pull request overview

This PR modernizes and standardizes the C++/WinRT embedded runtime headers and the cppwinrt tool sources by consistently qualifying fixed-width integer types with std::, replacing macro-based limits with std::numeric_limits, and preferring standard C++ library functions (std::memcpy, std::swprintf, etc.) over non-standard or platform-specific variants.

Changes:

• Standardize integer and size types across headers (std::uint32_t, std::size_t, etc.) and update related APIs/signatures.
• Replace macro-based bounds checks with std::numeric_limits and move C-library calls into std:: (std::memcpy, std::memset, std::wcslen, std::iswspace, std::abort, etc.).
• Add/update standard header includes to support the above changes.

Pull request overview

This PR standardizes the project’s C++ runtime usage by adding missing standard headers, fully qualifying fixed-width/size types with std::, replacing macro-based limits with std::numeric_limits, and preferring standard library functions (e.g., std::memcpy, std::swprintf) over non-standard or platform-specific variants.

Changes:

• Replace unqualified int32_t/uint32_t/..., size_t, ptrdiff_t, and C library calls with std::int32_t/..., std::size_t, std::ptrdiff_t, and std::-qualified functions.
• Add missing standard headers to ensure the new qualifications compile reliably (<cstdint>, <cstdlib>, <cwchar>, <cwctype>, <limits>, <cstdio>, <cctype>).
• Use std::numeric_limits instead of macros like UINT_MAX / INT_MAX for range checks.
