Auto merge of #68118 - skinny121:eager_lit_eval, r=varkor

perf: Eagerly convert literals to consts

Previousely even literal constants were being converted to an `Unevaluted` constant for evaluation later. This seems unecessary as no more information is needed to be able to convert the literal to a mir constant.

Hopefully this will also minimise the performance impact of #67717, as far less constant evaluations are needed.
