perf(options): avoid Lua<=>API roundtrips #40477

Problem:
- Lua<=>API roundtrips
- Although we prefer Lua for most business-logic code, doing this
  conversion in C makes sense in this case because:
  1. setting options is a hot path
  2. most of the options logic lives in C
  3. the current arrangement is MORE verbose and requires MORE code

Solution:
Move conversion to a C util.
- nvim_set_option_value passes the raw Object (scalar, Array, or Dict)
  to `object_as_optval_for()` which flattens it to the canonical `:set`
  string and validates the type.
- drop `convert_value_to_vim`, eliminate its roundtrip.
