SPM: Add MVE support for GNUARM toolchain

Add MVE support based on FPU.
1. Enable FPU usage by CONFIG_TFM_ENABLE_FP.
2. Enable Integer Vector Extension (MVE-I) usage by
   CONFIG_TFM_ENABLE_MVE.
3. Enable Floating-point Vector Extension (MVE-F) support by
   CONFIG_TFM_ENABLE_MVE_FP.
4. Rename CONFIG_TFM_ENABLE_FPU to CONFIG_TFM_ENABLE_CP10CP11
   to cover both coprocessor types.
5. TFM_SYSTEM_MVE deleted.
