Adds a parser and serializer for the EcoStd Module Metadata format RFC: https://github.com/ecostd/rfcs/pull/3 This adapts the existing experimental support for import std; to use the new parser. The CMAKE_CXX_STDLIB_MODULES_JSON is now the canonical variable for controlling how CMake discovers the stdlib module metadata, and is used directly by compiler detection. Toolchains can still override the __CMAKE::CXX## targets if they wish, either in conjunction with CMAKE_CXX_STDLIB_MODULE_JSON or not. It is possible to disable automatic detection of CMAKE_CXX_STDLIB_MODULE_JSON by setting it to the empty string. When available, the CMAKE_CXX_STDLIB_MODULE_JSON will be used to create all requested C++ stdlibs which do not already have targets.
