fix(compiler): Return ability arrow [LNG-258]

[DieMyst]

Description

After this PR functions in abilities can be called with <- symbol, as common functions.

func create() -> TestAb:
    arrow = () -> i8, i8:
        <- 42, 76
    <- TestAb(inner = InnerAb(arrow = arrow))

func test() -> i8, i8:
    ababab <- create()
    res1, res2 <- ababab.inner.arrow()
    <- res1, res2

Implementation Details

Handle ApplyPropertyRaw with IntoArrowRaw for CallArrowRawTag

LNG-258 Can't use returned ability arrow

aqua:

ability TestAb:
    arrow() -> i8

func create() -> TestAb:
    arrow = () -> i8:
        <- 42
    <- TestAb(arrow = arrow)

func test():
    ab <- create()
    res <- ab.arrow()

error:

---- Error: /home/vagrant/aqua/aqua-src/antithesis.aqua:15:12
15     res <- ab.arrow()
              ^^========
     Expected arrow call, got var{ab: ability TestAb{arrow: ∅ -> i8 :: ∅}}.IntoArrowRaw(arrow,i8,List())

this snippets do not pass parsing stage:

Ab <- create()
res <- Ab.arrow()

AB <- create()
res <- AB.arrow()

possible workaround:

Ab = create()
res <- Ab.arrow()

But using ← should be allowed

nit: Write Inline.prepend like Inline.append

Does this test the bug fix?
Let's create a separate test with:

• Abilities returned from func
• Abilities with names ab, Ab, AB (or similar in terms of case)
