tests: code_relocation: restrict Arm test to NXP platforms

Currently tests.application_development.code_relocation and
tests.application_development.code_relocation_kinetis scenarios are
restricted to specific NXP platforms only, so make filters more strict.

Also for frdm_k64f, which lacks of ITCM, relocation to ITCM must be
disabled.

Fixes #60167
