[SSR v2] add support for computed keys in wire config

[divmain]

See this thread. After #4807 is merged, the SSR compiler will have almost full support for wire adapters. However, this PR does not include support for computed keys in wire config. Instead, if non-identifiers are found for keys, an error is thrown during compilation.

Here is an example of that:

 @wire(getBar, { 
   ['computedStringLiteral']: '$prop', 
   [123n]: '$prop', 
   [321]: '$prop', 
   [null]: '$prop', 
   [undefined]: '$prop' 
 })

This issue should be considered fixed when an error "@wire config entry key must be an identifer" is no longer thrown during compilation of the above wire decorator, and the correct behavior from engine-* is reproduced in the SSR compiler.
