Wolfgang Pieb e13b33f132 [llvm-mca][NFC] Refactor handling of views that examine individual instructions,
including printing them.

Reviewers: andreadb, lebedev.ri

Differential Review: https://reviews.llvm.org/D86390

Introduces a new base class "InstructionView" that such views derive from.
Other views still use the "View" base class.
