JIT/AArch64: Code refactoring for macros (#7082)

* JIT/AArch64: Code refactoring for macros

Update the comments and rename arguments for some macros.

The following macros are renamed:
  SAFE_MEM_ACC_WITH_UOFFSET  -> MEM_ACC_64_WITH_UOFFSET
  SAFE_MEM_ACC_WITH_UOFFSET_32  -> MEM_ACC_32_WITH_UOFFSET
  SAFE_MEM_ACC_WITH_UOFFSET_BYTE -> MEM_ACC_8_WITH_UOFFSET
  MEM_STORE_BYTE_ZTS -> MEM_STORE_8_ZTS
  MEM_STORE_ZTS -> MEM_STORE_64_ZTS
  MEM_LOAD_ZTS -> MEM_LOAD_64_ZTS
  MEM_LOAD_BYTE_ZTS -> MEM_LOAD_8_ZTS
  ADD_IP_FROM_CST -> ADD_IP_WITH_CONST

The following macros are deprecated and removed:
  SET_Z_PTR, GET_Z_W2, SET_Z_W2

* Use MEM_ACCESS_*_WITH_UOFFSET

It's more accurate to use "MEM_ACCESS_*_WITH_UOFFSET" than
"MEM_ACC_*_WITH_UOFFSET".

* Revert the updates for macros ADD_IP_WITH_CONST and LONG_ADD_SUB_WITH_IMM

As pointed by Dmitry, (int32_t) (1LL << 32) would make the assertion
"TRUE", which is not expected by us.
