Make SwiftGodotMacros a dynamic library

[tishin]

To match the existing linking behavior of the base library.

Thank you - this makes sense.

Mhm, this actually became through some side effect a dependency of SwiftGodot which is needed to run things.

I will likely have to undo this later today.

There's no side effect dependency. If you you use macros, you also need SwiftGodotMacros to run things. Which embeds SwiftGodot in itself, so the first of driver's dependencies in tutorials is redundant:

.target(
    name: "SimpleRunnerDriver",
    dependencies: [
        "SwiftGodot",
        .product(name: "SwiftGodotMacros", package: "SwiftGodot")
    ],

It will work with a single dependency on 'SwiftGodotMacros':

.target(
    name: "SimpleRunnerDriver",
    dependencies: [
        .product(name: "SwiftGodotMacros", package: "SwiftGodot"),
    ],

Because SwiftGodotMacros statically depends on SwiftGodot target and embeds it.
