xtensa: include xtensa-types.h for xt-clang

Newer Xtensa toolchain needs to include xtensa-types.h so that
macros in tie.h can be used without compilation errors.
The exact verison needing this is unknown but first encountered
in RJ-2023.2. Tested with older toolchain and that did not
cause any compilation errors so just include xtensa-types.h
if xt-clang is used. Haven't seen newer toolchains being
generated with xcc, so skip that for now.

Note that Zephyr SDK and the public HAL in Zephyr do not provide
this file.
