Bump scala-library from 2.12.7 to 2.12.8

[dependabot-preview]

Bumps scala-library from 2.12.7 to 2.12.8.

Release notes

Sourced from scala-library's releases.

Scala 2.12.8

This release fixes two regressions that appeared in 2.12.7:

• Don't reject views with result types which are TypeVars (#7295)
• Don't emit static forwarders (which simplify the use of methods in top-level objects from Java) for bridge methods (#7469)

The second fix is not binary compatible: the 2.12.8 compiler omits certain methods that are generated by earlier 2.12 compilers. However, we beleive that these methods are never used and existing compiled code will continue to work. See the pull request description for more details.

Further highlights of this release:

• Improved inference of parameter types for eta-expansion (#7340)
• Emit detailed compiler trace under -Yprofile-trace (#7364)
• Make the compiler output deterministic under incremental compilation (#7203)

For more details, check out all closed bugs
and merged PRs.

As usual for minor releases, Scala 2.12.8 is binary compatible with the whole Scala 2.12 series.
