[PATCH 04/13] arm-bsp: corstone1000: Add PLATFORM_IS_FVP toggle for FVP/FPGA builds

Introduces PLATFORM_IS_FVP to differentiate between FVP and FPGA builds.
Adds platform-specific CMake files for corstone1000-fvp and corstone1000-mps3,
and updates platform.cmake to use this toggle.

This commit also adds the TS_PLATFORM variable to corstone1000-fvp.conf
and corstone1000-mps3.conf, explicitly defining platform identifiers
for Trusted Services. This ensures a consistent and clear distinction
between the FVP and MPS3 builds within the build system.

These changes improve maintainability and platform-specific handling
by making it easier to reference the correct target platform
in configurations and scripts.
