  [VPlan] Separate out logic to manage IR flags to VPIRFlags (NFC). (#140621)

This patch moves the logic to manage IR flags to a separate VPIRFlags
class. For now, VPRecipeWithIRFlags is the only class that inherits
VPIRFlags. The new class allows for simpler passing of flags when
constructing recipes, simplifying the constructors for various recipes
(VPInstruction in particular, which now just has 2 constructors, one
taking an extra VPIRFlags argument.

This mirrors the approach taken for VPIRMetadata and makes it easier to
extend in the future. The patch also adds a unified flagsValidForOpcode
to check if the flags in a VPIRFlags match the provided opcode.
