xtensa: add __umulsidi3 helper
xtensa gcc-13 has changed multiplication handling and may now use
__umulsidi3 helper where it used to use __muldi3. As a result building
the kernel with the new gcc may fail with the following error:
linux/init/main.c:1287: undefined reference to `__umulsidi3'
Fix the build by providing __umulsidi3 implementation for xtensa.
