cmake: compiler/xt-clang: add -Wno-unknown-warning-option

Browse source 
xt-clang is usually based on older version of clang, and
Zephyr main targets more recent versions. Because of this,
some newer compiler flags may cause warnings where twister
would mark as test being failed. To workaround that,
add -Wno-unknown-warning-option to suppress those warnings.

Fixes #84138
