feat(arm): move GPT setup to common BL source
As of now, GPT setup is being handled from BL2 for plat/arm platforms. However, for platforms having a separate entity to load firmware images, it is possible for BL31 to setup the GPT. In order to address this concern, move the GPT setup implementation from arm_bl2_setup.c file to arm_common.c. Additionally, rename the API from arm_bl2_gpt_setup to arm_gpt_setup to make it boot stage agnostic.

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.

feat(partition): add support to use backup GPT header
Currently we just use primary GPT header which is located in second entry after MBR header, but if this block is corrupted or CRC mismatch occurs we could try to use the backup GPT header located at LBAn and GPT entries following this from LBA-33.
Add suitable warning messages before returning any errors to identify the cause of issue.
