Introduce BTI support in ROMLIB
When TF-A is compiled with BTI enabled, the branches in the ROMLIB
jumptable must be preceded by a "bti j" instruction.
Moreover, when the additional "bti" instruction is inserted, the
jumptable entries have a distance of 8 bytes between them instead of 4.
Hence, the wrappers are also modified accordinly.
If TF-A is compiled without BTI enabled, the ROMLIB jumptable and
wrappers are generated as before.
