[MC] Unhide the target-abi option.

[topperc]

This option is very important for RISC-V as it controls calling convention and a field in the ELF header. It is used in a large number of RISC-V lit tests.

Expose the option to -help.

Fixes one issue raised in #123077

I use this all the time and didn't know it was hidden. Making it visible is a good improvement!
