[llvm] [RISCV] Rename Relocation QC_E_JUMP_PLT to QC_E_CALL_PLT (PR #143998)

[Sam Elliott via llvm-commits]

https://github.com/lenary created https://github.com/llvm/llvm-project/pull/143998

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 semantics and definition of this relocation are unchanged. The new
name reflects that instructions with the relocation should be assumed to

relocation.
