SNOW-755844: Pointer datatype *time.Time returns <nil> value

[sfc-gh-ext-simba-jl]

Issue: https://github.com/snowflakedb/snowflake-sdks-drivers-issues-teamwork/issues/246

Starting with gosnowflake 1.6.13, the use of a pointer *time.Time type in user-defined structures used to perform updates/inserts has silently stopped working, and nil value is used instead of the value it points to.
This PR fixes the regression introduced by PR #642. All array binding insertion using []interface{} will now be wrapped in the interfaceArrayBinding struct, instead of assuming them as the reflect.Slice and reflect.Struct types.

type interfaceArrayBinding struct {
	hasTimezone       bool
	tzType            timezoneType
	timezoneTypeArray interface{}
}
