LAPACK: annotate size check in lacpy! with @noinline for reduced latency

[jishnub]

The @noinline annotation on the size check appears to reduce latency in a second call with different argument types:

julia> using LinearAlgebra

julia> A = rand(2,2); B = similar(A);

julia> @time LAPACK.lacpy!(B, A, 'U');
  0.032585 seconds (29.80 k allocations: 1.469 MiB, 99.84% compilation time)

julia> A = rand(Float32,2,2); B = similar(A);

julia> @time LAPACK.lacpy!(B, A, 'U');
