fix(libdmr): strip LoongArch out of Platform::Mips

[MingcongBai]

LoongArch is not MIPS-based Loongson and exhibits significantly different performance characteristics (try ~50 - 100% faster with current hardware versus 3A4000).

There is no need to strip out functionalities in order to obtain acceptable performance. The current 3A6000 processors can easily keep up with 10th Gen Intel i3 processors.

关键摘要:

• 在compositing_manager.cpp文件中，注释应该准确反映代码的功能，而不是包含拼写错误。建议将注释修改为"match shenwei"，以避免混淆。
• 在compositing_manager.h文件中，注释应该保持简洁明了，避免使用复杂的句子和过多的细节。当前的注释"MIPS-based Loongson"已经足够清晰地表达了平台的意图。

是否建议立即修改:

• 是，注释应该准确反映代码的功能和意图，以便于理解和维护代码。
