Automated release for v0.16.0-r3.

Source commit: e4847c181e96103f297ca9f31cc9546693392935

Highlights

• This release introduces Zig toolchain support for version 0.16.0 with downstream ESP Xtensa enhancements.
• C and C++ programming languages now support __int128 and unsigned __int128, enabling advanced data handling with new typedefs and built-in operations.

Changes

• New Features:

  • Implemented support for __int128_t and __uint128_t in C and C++.
  • Added builtin functions to handle atomic operations and overflow with __int128.
  • Included arithmetic operations for unsigned __int128.

• Regression Test Enhancements:

  • Added comprehensive regression tests for __int128, including atomic operations, arithmetic behavior, overflow checks, and its integration with C++.

Notes

• This release focuses on Xtensa compiler/backend improvements, particularly the addition of C int128 support.
• Validation coverage has been expanded with new tests to ensure robust handling of __int128 types and their operations.
