refactor(arm): rename L0/L1 GPT base macros

In accordance with common naming conventions, macros specifying the base
address of a region typically use the prefix "BASE" combined with the
region name, rather than "ADDR_BASE."

Currently, the macros defining the base addresses for L0 and L1 GPT
tables within `arm_def.h` are named "ARM_L0_GPT_ADDR_BASE" and
"ARM_L1_GPT_ADDR_BASE" respectively. To adhere to the established naming
convention, rename these macros as "ARM_L1_GPT_BASE" and
"ARM_L0_GPT_BASE" respectively.
