Unhardcode the CMAKE_CONFIGURATION_TYPES values
This removes duplicated code for per-config variable initialization by
providing a `cmake_initialize_per_config_variable(<PREFIX> <DOCSTRING>)`
function.

This function initializes a `<PREFIX>` cache variable from `<PREFIX>_INIT`
and unless the `CMAKE_NOT_USING_CONFIG_FLAGS` variable is defined, does
the same with `<PREFIX>_<CONFIG>` from `<PREFIX>_<CONFIG>_INIT` for every
`<CONFIG>` in `CMAKE_CONFIGURATION_TYPES` for multi-config generators or
`CMAKE_BUILD_TYPE` for single-config generators.

CMAKE_<LANG>_FLAGS_<CONFIG>_INIT
--------------------------------
Value used to initialize the :variable:`CMAKE_<LANG>_FLAGS_<CONFIG>` cache
entry the first time a build tree is configured for language ``<LANG>``.
This variable is meant to be set by a :variable:`toolchain file
<CMAKE_TOOLCHAIN_FILE>`. CMake may prepend or append content to
the value based on the environment and target platform.
See also :variable:`CMAKE_<LANG>_FLAGS_INIT`.
