[Enhance] Enable full precision training on Ascend NPU. (#3085)
## Motivation

We will support full precision training on the next generation Ascend
NPU, so there is no need to enable mixed precision by default.

## Modification

Determine whether the current chip supports full precision training, and
automatically enable mixed precision.

## BC-breaking (Optional)

Not affected.

## Use cases (Optional)

We have verified the correctness on the Ascend NPU.
