  [RISCV,GISel] Unconditionally use MO_PLT for calls (#72355)

All known linkers handle R_RISCV_CALL and R_RISCV_CALL_PLT in the same
way (GNU ld since
https://sourceware.org/pipermail/binutils/2020-August/112750.html).

MO_CALL is for R_RISCV_CALL, a deprecated relocation type. We don't
migrate away from MO_CALL yet.
For GISel we don't have the output difference concern and should weigh
more on simplicity.
