util/spd_tools: Add support for LP5X SPDs
This commit adds support for LP5X SPDs. The SPD format is identical to LP5 except that the memory type is set to 0x15 instead of 0x13. Since they are essentially the same, LP5/5X parts share the same parts JSON file and SPD directory. LP5X parts are distinguished by the optional `lp5x` attribute. This commit also updates two existing LP5X memory parts with the correct attribute. BUG=b:242765117 TEST=Generated SPDs, verified that SPDs generated from LP5X parts match their LP5 counterparts except for memory type byte.
