Allow custom intermediate directory layout in dependir/objectir/targetdir

[xq114]

你在什么场景下需要该功能？

目前xmake生成的中间目录结构统一为plat/arch/mode形式，例如.deps//windows/x64/release/...。目录结构的用途是区分config不让不同config的文件混在一起，然而实际上固定的目录结构并不能达成这一目标（很多时候plat/arch/mode都是定死的，产生区别的是其他config），需要灵活指定中间目录结构。

描述可能的解决方案

增加一个api设置中间目录结构；最好可以在on_config脚本域指定，这样可以实现一些复杂一点的操作，例如根据所有config计算一个hash作为中间目录

描述你认为的候选方案

In what scenario do you need this feature?

Currently, the intermediate directory structure generated by xmake is unified in the form of plat/arch/mode, such as .deps//windows/x64/release/.... The purpose of the directory structure is to distinguish configs and prevent files from different configs from mixing together. However, in fact, a fixed directory structure cannot achieve this goal (many times plat/arch/mode are fixed, and the difference is other configs) , need to flexibly specify the intermediate directory structure.

Describe possible solutions

Add an API to set the intermediate directory structure; it is best to specify it in the on_config script field, which can achieve some more complex operations, such as calculating a hash as an intermediate directory based on all configs

加了个 build.intermediate_directory policy，可以禁用生成中间目录。set_policy("build.intermediate_directory", false)

https://github.com/xmake-io/xmake/pull/5283

然后，你直接 set_targetdir/set_objectdir/set_dependir 设置就行了。。但只能在 on_load 里面改，on_config 不行，太滞后
