Promote the build system v2 functions and macros used by the
examples/build_system/cmakev2 examples to the generated API reference,
document the component-scope and version variables, the public build
properties, and the public component properties, and add cmakev2
build_property and component_property directives with dedicated Build
Properties and Component Properties sections to the esp-docs extension.
