try_compile: Optionally forward custom platform variables to test project
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list of custom variables to be forwarded to a `try_compile` test project. This will be useful for platform information modules or toolchain files to forward some platform-specific set of variables from the host project (perhaps set in its cache) to the test project so that it can build the same way.

+List of variables that the :command:`try_compile` command source file signature
+must propagate into the test project in order to target the same platform as

+
+This variable should not be set by project code. It is meant to be set by

+toolchain file when used with :variable:`CMAKE_TOOLCHAIN_FILE`.
