`BUILD_INTERPOLATION` and `BUILD_TEMPLATE` perform unnecessary refcount operations

Feature or enhancement

Proposal:

BUILD_INTERPOLATION and BUILD_TEMPLATE call _PyInterpolation_Build and _PyTemplate_Build respectively, and then decref their arguments. All other BUILD instructions call a "steal" function, to avoid the unnecessary incref then decref. BUILD_INTERPOLATION and BUILD_TEMPLATE should do the same.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

从 BUILD_INTERPOLATION 和 BUILD_TEMPLATE 指令处理器以及 _PyInterpolation_Build 和 _PyTemplate_Build 入口点开始。将它们与其他 BUILD 指令的 steal 函数进行比较；完成的标准是这些指令避免不必要的 incref/decref 操作。
