try_compile: Add SOURCE_FROM_{ARG,VAR,FILE}
Add ability to "feed" try_compile
(and try_run
) sources more directly, either from literal content, or from a CMake variable which contains literal content, or from a file. This saves the user from needing a separate step to write the content to a file, and allows for the sources to only exist in the scratch directory.
Issue: #22799 (closed)
