core: add YAML 1.2 support for FileStorage #28482

Fixes: #26363
CI Update: https://github.com/opencv/ci-gha-workflow/pull/306

Summary: 
- Bool true/false literals support
- Header-less YAMLs support for Python YAML module compatibility. Header-less files are parsed as YAMLs by default
- Added FORMAT_YAML_1_0 flag to FileStorage for fallback.
- New YAML1.2 header

Testing: 
- Added Core_InputOutput.YAML_1_2_Compatibility test case in test_io.cpp.
- Added YAML interop test in Python
