[Feature] create FunctionRegistry based on argument type not argument count

[walterddr]

Currently, Pinot's FunctionRegistry registers and looks up function based on name and function argument count. this causes a problem that we can't register 2 functions with the same name but different function argument types. for example sum(int, int) and sum(long, long)

Propose to change a FunctionRegistry to accept lookup based on argument type.

• Map<String, Map<Integer, FunctionInfo>> FUNCTION_INFO_MAP; will be changed to be of type: Map<String, Map<Collection<DataType>, FunctionInfo>>.
• Lookup will now support both argument count and argument type list.
• Lookup should also support same argument signature, but different return type, for example: CAST(intCol AS 'long') and CAST(intCol AS 'double') will have identical arg signature cast(int, string) but different return type. see: [bug] CAST after expression causes weird exception #8424

Note: this depends on LiteralContext in #8596 as there's a backward incompatible Literal argument type issue, however to some extent we can ignore this limitation by always returning the first matching argument count function
