feat(wire): allow arbitrary computed properties in @wire config @W-17206172

[wjhsf]

Details

In #3955, we updated @wire to allow configs with computed properties, e.g. { [symbol]: '$prop' }. Because of the way the config gets compiled, a computed key like [Math.random()] would return a different value every time. To avoid that, the original implementation for computed properties only allowed a limited subset of expressions (specifically, literals and const variables). In this PR, we update the compiler to store a snapshot of the computed keys, so that the values do not change. This enables us to now allow any arbitrary value as a config key.

As an example, these all used to be forbidden, but are now allowed.

@wire(adapter, { [{ toString: Date.now }]: 'weird but valid JS' }) one;
@wire(adapter, { [`number: ${Math.random()`]: 12345 }) two;
import something from 'somewhere';
@wire(adapter, { [something]: '$value' }) three;

Closes #3956.

Nobody asked for this, and there's some risk in things getting explode-y, so we'll hold off on the implementation.
