bors ae06b79dcb Auto merge of #139640 - Zoxc:big-file-encoder, r=saethlin 
Bump `FileEncoder` buffer size to 64 kB

This helps avoid file system overhead on Windows. The improvement are probably reduced a bit on other platforms. Making the buffer size even larger does further improve performance, but that increase memory use further.
