`SAI_SWITCH_ATTR_TEMP_LIST` returns temperature values rounded to whole degrees Celsius. This discards sub-degree precision that is available from the hardware, making it unsuitable for applications that require finer thermal granularity.

SAI_SWITCH_ATTR_TEMP_LISTreturns temperature values rounded to whole degrees Celsius. This discards sub-degree precision that is available from the hardware, making it unsuitable for applications that require finer thermal granularity.Attributes added to saiswitch.h:
SAI_SWITCH_ATTR_TEMP_LIST_RAW
SAI_SWITCH_ATTR_TEMP_BASE_TEN_PRECISION
Motivation: The existing SAI_SWITCH_ATTR_TEMP_LIST returns temperatures rounded to whole degrees Celsius, losing sub-degree precision available from hardware. These two new attributes are added to expose unrounded readings and define their unit, enabling applications to consume full hardware precision without affecting existing consumers of TEMP_LIST.
