riscv: alloc space exhausted

When trying to run qemu-riscv64_smode_defconfig with 32 harts booting fails. The debug UART shows a message alloc space exhausted 32 is the current maximum number of harts for machine virt in QEMU 7.0. Raise the default for SYS_MALLOC_F_LEN to 16 KiB. Move the setting to /Kconfig where we define SYS_MALLOC_F_LEN for other architectures too.
