This patch aims to improve the definitions of BTI and PAC based PLTs.
The following changes are made:
   * PLT0 does not need PAC instructions since the PLTGOT[2] (and PLTGOT[1])
     are readonly so they cannot be corrupted at runtime. Thus both PAC plt0
     and BTI+PAC plt0 are removed and we can use basic plt0 and BTI plt0
     instead, respectively.
   * We can remove the extra padding nops when we add the new bti instructions.
     BTI plt0 and BTI TLSDESC plt are updated.
   * For better performance PLTn could be padded to 24bytes. Both BTI pltn and
     PAC pltn are updated.
