    toolchain: gcc: switch default to 13
    
    Use GCC 13 instead of GCC 12 by default.
    
    All target kernels are building with GCC 13.
    Most packages from the feed are building fine.
    
    The root file systems is getting a little bit smaller for MIPS 32 BE
    and aarch64.
    
    With GCC 12 I got these sizes for lantiq/xrx200:
    7,005,867 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
    
    With GCC 13 I got these sizes for lantiq/xrx200:
    6,989,754 openwrt-lantiq-xrx200-tplink_tdw8970-initramfs-kernel.bin
    
    With GCC 12 I got these sizes for armsr/armv8:
    13,083,836 openwrt-armsr-armv8-generic-ext4-combined.img.gz
     4,900,240 openwrt-armsr-armv8-generic-ext4-rootfs.img.gz
    20,142,592 openwrt-armsr-armv8-generic-kernel.bin
    
    With GCC 13 I got these sizes for armsr/armv8:
    13,068,966 openwrt-armsr-armv8-generic-ext4-combined.img.gz
     4,893,078 openwrt-armsr-armv8-generic-ext4-rootfs.img.gz
    20,142,592 openwrt-armsr-armv8-generic-kernel.bin
