[compiler] Fix false positive for useMemo reassigning context vars (#34904)
Within a function expression local variables may use StoreContext for
local context variables, so the reassignment check here was firing too
often. We should only report an error for variables that are declared
outside the function, ie part of its `context`.

React Compiler

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

More information about the design and architecture of the compiler are covered in the Design Goals.

More information about developing the compiler itself is covered in the Development Guide.
