[PATCH] module: Add comment explaining purpose of module_decompress.c

[Mishchneko Sergey]

Hi,

This patch adds a header comment to kernel/module/decompress.c to 
clarify its purpose.

The file handles decompression of loadable kernel modules using multiple 
formats (gzip, xz, zstd), and this comment helps new contributors 
understand the role of this file more easily.
