924060929 cf04c9c300 [enhancement](Nereids) refine and speedup analyzer (#31792) (#32111)
## Proposed changes
1. check data type whether can applied should not throw exception when real data type is subclass of signature data type
2. merge `SlotBinder` and `FunctionBinder` to `ExpressionAnalyzer` to skip rewrite the whole expression tree multiple times.
3. `ExpressionAnalyzer.buildCustomSlotBinderAnalyzer()` provide more refined code to bind slot by different parts and different priority
4. the origin slot binder has O(n^2) complexity, this pr use `Scope.nameToSlot` to support O(n) bind
5. modify some `Collection.stream()` to `ImmutableXxx.builder()` to remove some method call which are difficult to inline by jvm in the hot path, e.g. `Expression.<init>` and `AbstractTreeNode.<init>`
6. modify some `ImmutableXxx.copyOf(xxx)` to `Utils.fastToImmutableList(xxx)` to skip addition copy of the array
7. set init size to `Immutable.builder()` to skip some useless resize
8. lazy compute and cache some heavy operations, like `Scope.nameToSlot` and `CaseWhen.computeDataTypesForCoercion()`
