[PATCH v2] Update RISC-V relocations

[PATCH v2] Update RISC-V relocations

[Andreas Schwab]

This updates the list of RISC-V relocations from the ELF psABI as of Apr
2024.  It removes binutils-internal only relocations that were never part
of actual object files.  The GNU_VTINHERIT and GNU_VTENTRY relocations
were never used because the corresponding GCC option -fvtable-gc was never
supported on RISC-V.
---
v2: Remove GPREL relocations.  They were recently removed again from the
ABI, as they are only supposed to be linker-internal.
