reproducible builds: inner functions are not consistently generated on Scala 3

[raboof]

reproducing 1.1.0-M1 with set ThisBuild / net.bzzt.reproduciblebuilds.ReproducibleBuildsPlugin.reproducibleBuildsCheckResolver := DefaultMavenRepository; ++3.3; clean; reproducibleBuildsCheck showed two nondeterminisms for me in pekko-http_3-1.1.0-M1.jar :

• In org/apache/pekko/http/scaladsl/server/directives/FileUploadDirectives.class, one build had default·Directive·storeUploadedFile$$anonfun$1$(final·FileUploadDirectives·$this,·final·String·fieldName$1,·final·Function1·destFn$1,·final·RequestContext·ctx) and default·/*·synthetic·*/·Directive·storeUploadedFile$$anonfun$1(final·String·fieldName$1,·final·Function1·destFn$1,·final·RequestContext·ctx), the other hadn't
• In org/apache/pekko/http/scaladsl/server/directives/RangeDirectives.class, one build didn't have default·Directive·applyRanges$1$(final·RangeDirectives·$this,·final·LoggingAdapter·log$3,·final·RoutingSettings·settings$6,·final·Seq·ranges), the other did.

Note default·Directive·storeUploadedFile$$anonfun$1$(final·FileUploadDirectives·$this,·final·String·fieldName$1,·final·Function1·destFn$1,·final·RequestContext·ctx) is a function with an actual implementation - if that's not there, does it even work? Or is it duplicated somewhere?

Possibly related to scala/scala3#18248

Saw something similar in the 1.1.0 release, but now with 'withRangeSupport': https://arnout.engelen.eu/reproducible-builds-diffoscope-output-pekko-http_3-1.1.0.jar/
