The new reflection based IO autowrapping for compatibility mode Modules
would previously throw a NullPointerExceptions if any hardware were
constructed in the Module before "val io" was initialized. The logic is
now more robust for this case.

#naming implies within the current file. Removing the # refers to a file in the current directory.

This only includes a merge-based flow which will presumably be
squash-and-merged for any merged PRs. It is possible to do this with
rebasing but it is tricky and hard to describe in a fool-proof way.

* Enable CI for 3.5.x branch
* Enable Mergify for 3.5.x branch
* Drop 3.5.x from Mergify

Add scalafmt configuration and apply it.

Command:
sbt scalafmtAll

Can be run in two ways:
* sbt scalaFmtAll
* mill mill.scalalib.scalafmt.ScalafmtModule/reformatAll __.sources

Generation script is chisel-repo-tools/scripts/mergify.sc

* New Feature: Add a Select.ios that works with Definition/Instance
* BugFix: isA now truly ignores type parameters

Note that I am keeping the change making Arg sealed.

- Shows groups of field names that share a common id (i.e. aliased)
