Collect callable: just forward to copy when possible

[nsajko]

Helps effect inference infer nothrow.

Fixes #43

Before:

julia> v(x) = collect_as(FixedSizeVector, x)
v (generic function with 1 method)

julia> m(x) = collect_as(FixedSizeMatrix, x)
m (generic function with 1 method)

julia> Base.infer_effects(v, Tuple{FixedSizeVectorDefault{Float32}})
(!c,!e,!n,+t,+s,!m,!u,+o,!r)

julia> Base.infer_effects(m, Tuple{FixedSizeMatrixDefault{Float32}})
(!c,!e,!n,+t,+s,!m,!u,+o,!r)

After:

julia> v(x) = collect_as(FixedSizeVector, x)
v (generic function with 1 method)

julia> m(x) = collect_as(FixedSizeMatrix, x)
m (generic function with 1 method)

julia> Base.infer_effects(v, Tuple{FixedSizeVectorDefault{Float32}})
(!c,!e,+n,+t,+s,!m,!u,+o,!r)

julia> Base.infer_effects(m, Tuple{FixedSizeMatrixDefault{Float32}})
(!c,!e,+n,+t,+s,!m,!u,+o,!r)

julia> VERSION
v"1.13.0-DEV.682"
