  [flang][CUDA] Keep host literals from using unified-memory generic distance (#201257)

Fix CUDA generic resolution under `-gpu=mem:unified` so unattributed
literals and expression temporaries are not treated as unified-memory
actuals.

Previously, a host scalar literal such as `1.0` could score as
compatible with a `DEVICE` dummy and incorrectly select the
device-scalar overload. This could pass a host stack address to a device
helper and fail at runtime. The fix applies the unified/managed memory
distance columns only to symbol-backed actuals.
