refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3

refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3

BL2_AT_EL3 is an overloaded macro which has two uses:
1. When BL2 is entry point into TF-A(no BL1)
2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).

BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

refactor(libc): clean up dependencies in libc

- Removing platform dependencies from libc modules.
- Replacing panicking with actual error handling.
- Debug macros are included indirectly from assert.h. Removing
"platform_def.h" from assert.h and adding "common/debug.h"
where the macros are used.
- Removing hack for fixing PLAT_LOG_LEVEL_ASSERT to 40.
Instead removing assert with expression, as this
does not provide additional information.
