0df3fe79 - Adds interpolation syntax to `Threads.@spawn`, to evaluate arguments immediately (#33119)

Adds interpolation syntax to `Threads.@spawn`, to evaluate arguments immediately (#33119) Adds $-interpolation syntax to `@async` and `Threads.@spawn`, to evaluate arguments immediately. Add the ability to evaluate some parts of a `@spawn`/`@async` immediately, in the current thread context. This prevents variables being "boxed" in order to capture them in the closure, exactly the same as wrapping them in a let-block locally. For example, `$x` expands like this: ```julia julia> @macroexpand @async $x + 2 quote #= task.jl:361 =# let var"##454" = x #= task.jl:362 =# local var"#9#task" = Base.Task((()->begin #= task.jl:358 =# var"##454" + 2 end)) #= task.jl:363 =# if $(Expr(:islocal, Symbol("##sync#95"))) #= task.jl:364 =# Base.push!(var"##sync#95", var"#9#task") end #= task.jl:366 =# Base.schedule(var"#9#task") #= task.jl:367 =# var"#9#task" end end ```
