描述

We want to have fast iteration speed on code generation. https://github.com/project-chip/connectedhomeip/blob/master/scripts/py_matter_idl/matter/idl/generators/cpp/sdk/sdk_generator.py#L120 currently generates a LOT of files and could benefit from paralelization

Update code logic to do parallel generation and test out if this improves runtime (i.e. if it is worth it - this issue was created on the assumption that it is, however we should verify that).

We also do file formatting and those seem to call one single exec to format many files at once. We should investigate if splitting files per cpu count improves formatting (i.e. is clang-format and kotlin-format single threaded or multi-threaded?)

研究方向
Investigate the file scripts/py matter idl/matter/idl/generators/cpp/sdk/sdk generator.py at line 120 to understand the current sequential generation. Implement parallel generation using Python's concurrent.futures module. Measure runtime before and after to confirm improvement. Additionally, examine clang format and kotlin format to determine if they are single threaded; if so, split the file list by CPU count and format in parallel. Report the performance results in the issue.
