[aarch64 linux ci] missing sccache binaries for aarch64 linux platform #121559
Description
🐛 Describe the bug
Currently pytorch CI build infrastructure maintains sccache binaries only for x86 architecture. We need the aarch64 linux binaries to speed up the aarch64 ci workflows. Currently aarch64 linux workflow is crashing if sccache is enabled because x86 binaries are pulled.
