In order to make the framework code structure clearer and more readable, it encapsulates multiple calling interfaces, uses clearer variable names, and draws a comparison diagram before and after lowering, so that developers can better understand the code. issue: https://e.gitee.com/open_harmony/dashboard?issue=I4U02P Signed-off-by: xujie <xujie101@huawei.com> Change-Id: Ied4933d8eac5e4b7b50c894ae496d7cf8d1ff1b0
