The rti-need of an instantiation is not the same as the rti-need of the
instantiated generic function. The generic function might not use its
type arguments but the instantiation still needs the type arguments for
equality.
dart2js implements generic function instantiation by creating instances
of a helper class that is a subclass of `Closure`. The helper class needs
its type parameters since they are used in `==` and `toString()` methods.
The fix for #47054 is to add the dependency of the helper class type
parameters on the instantiation type arguments.

This CL avoids creating locals using KernelToLocalsMap when computing
closure data for the J-model. Instead the closure data uses
ir.VariableDeclaration, JTypeVariable, and internal locals (ThisLocal
and BoxLocal) internally, and the accessor function require passes
a KernelToLocalsMap to convert the internal model to a Locals upon use.
The converted Locals are cached internal for performance only.
This prepares for splitting the GlobalLocalsMap and KernelToLocalsMap
from the JClosedWorld.
Previously landed in https://dart-review.googlesource.com/c/sdk/+/180820
but reverted.
