[RISCV] Rename Relocation QC_E_JUMP_PLT to QC_E_CALL_PLT

The semantics and definition of this relocation are unchanged. The new
name reflects that instructions with the relocation should be assumed to
clobber non-callee-saved registers, as with the R_RISCV_CALL_PLT
relocation.

The name was changed in v0.2 of the ABI Extensions:
https://github.com/quic/riscv-elf-psabi-quic-extensions/releases/tag/v0.2

The corresponding llvm change is llvm/llvm-project#143998
