[RFC PATCH v3 27/28] arm/Kconfig: Always select SEMIHOSTING when TCG is present |

We are about to enable the build without TCG, so CONFIG_SEMIHOSTING
and CONFIG_ARM_COMPATIBLE_SEMIHOSTING cannot be unconditionally set in
default.mak anymore. So reflect the change in a Kconfig.
Instead of using semihosting/Kconfig, use a target-specific file, so
that the change doesn't affect other architectures which might
implement semihosting in a way compatible with KVM.
The selection from ARM_v7M needs to be removed to avoid a cycle during
parsing.
