Declare helper functions for TypeScript

[bterlson]

This lets you write code like:

const hi = namekey("hi");
<ts.SourceFile path="test1.ts">
  {code`
    const ${decl(hi)} = 12;
    console.log(${hi});
  `}
</ts.SourceFile>

@alloy-js/core - fix ✏️

Fix a bug where tracing would track additional signals.

@alloy-js/typescript - feature ✏️

Introduce decl, declType, and declMember functions to declare a symbol given a namekey and return the new symbol name. Allows avoiding the use of declaration components if desired.
