liblzma: Rename arch-specific CRC functions and macros.
CRC_CLMUL was split to CRC_ARCH_OPTIMIZED and CRC_X86_CLMUL. CRC_ARCH_OPTIMIZED is defined when an arch-optimized version is used. Currently the x86 CLMUL implementations are the only arch-optimized versions, and these also use the CRC_x86_CLMUL macro to tell when crc_x86_clmul.h needs to be included. is_clmul_supported() was renamed to is_arch_extension_supported(). crc32_clmul() and crc64_clmul() were renamed to crc32_arch_optimized() and crc64_arch_optimized(). This way the names make sense with arch-specific non-CLMUL implementations as well.
