Rename 'main' on some backends (#7105)
* Rename 'main' on some backednds
Fixes #5542
Some backends like cuda, metal, cpu do not allow 'main' as the entry
point. This commit adds a new warning that is emitted when a program
uses main as the entry point. In addition to emitting the warning, it
internally renames the entry point to "main_". It also adds a test to
check these for the three backends.
* format code
* move test to diagnostics
* rename test to diagnostic
* generate unique name
