Andrew Scott 35d61c11fd test(core): Add benchmark for transplanted views when insertion is dirty (#36722)
The current benchmark for transplanted views only exercises the path
when the declaration location is dirty and the insertion is not. This
test adds a benchmark for when both insertion and declaration are dirty.
