f63702de0f scheduler: return UnschedulableAndUnresolvable when node capacity is insufficient 
Currently, the NodeResourcesFit plugin always returns Unschedulable when a pod's
resource requests exceed a node's available resources. However, when a pod's
requests exceed the node's total allocatable, preemption cannot help since even
an empty node would not have enough resources.

This change modifies the NodeResourcesFit plugin to return UnschedulableAndUnresolvable
when a pod's resource requests exceed the node's total allocatable. This helps
optimize the scheduling process in large clusters by:
1. Reducing the number of candidate nodes that need to be considered for preemption
2. Providing clearer feedback about unresolvable resource constraints
3. Improving scheduling performance by avoiding unnecessary preemption calculations

The change is particularly beneficial in heterogeneous clusters where node sizes
vary significantly, as it helps quickly identify nodes that are fundamentally
too small for certain pods.

6db40446de Scheduler changes: 
1. Use pod-level resource when feature is enabled and resources are set at pod-level
2. Edge case handling: When a pod defines only CPU or memory limits at pod-level (but not both), and container-level requests/limits are unset, the pod-level requests stay empty for the resource without a pod-limit. The container's request for that resource is then set to the default request value from schedutil.

`UnschedulableAndUnresolvable` if the feature gate is disabled to avoid
