Several free functions and helper functions across the SBE VM still take raw (value::TypeTags xTag, value::Value xValue) parameter pairs. Now that the builtin functions and generic helpers have been migrated to TagValueView/TagValueMaybeOwned, their call sites already hold TagValueView objects and split them manually with .tag, .value. Collapsing each pair into a single TagValueView parameter removes that splitting and keeps the value together as a unit.

Functions in scope (at minimum):

• getDate(TypeTags, Value) in vm_datetime.cpp — callers in block-processing loops pass raw (tag, val) loop variables
• Any additional utility functions across vm_builtin_*.cpp, vm_block.cpp, and other SBE VM files that follow the same (TypeTags xTag, Value xValue) pattern and are called exclusively from converted builtins

This is a catch-all for utility-function parameter cleanup that is out of scope for the individual per-file builtin refactor tickets in SPM-4577.
