feat(arm): retrieve GPT related data from platform

For RME-enabled platforms, initializing L0 and L1 tables and enabling
GPC checks is necessary. For systems using BL2 to load firmware images,
the GPT initialization has to be done in BL2 prior to the image load.
The common Arm platform code currently implements this in the
"arm_bl2_plat_gpt_setup" function, relying on the FVP platform's
specifications (PAS definitions, GPCCR_PPS, and GPCCR_PGS).

Different Arm platforms may have distinct PAS definitions, GPCCR_PPS,
GPCCR_PGS, L0/L1 base, and size. To accommodate these variations,
introduce the "plat_arm_get_gpt_info" API. Platforms must implement
this API to provide the necessary data for GPT setup on RME-enabled
platforms. It is essential to note that these additions are relevant to
platforms under the plat/arm hierarchy that will reuse the
"arm_bl2_plat_gpt_setup" function.

As a result of these new additions, migrate data related to the FVP
platform to its source and header files.
