GPU: method disambiguation from GPUArraysCore getindex

[fda-tome]

There is an ambiguous method for GPUArrays:

ERROR: MethodError: getindex(::CuArray{Bool, 2, CUDA.DeviceMemory}, ::ArrayDomain{2, Tuple{UnitRange{Int64}, UnitRange{Int64}}}) is ambiguous.

Candidates:
  getindex(A::GPUArraysCore.AbstractGPUArray, Is...)
    @ GPUArrays ~/.julia/packages/GPUArrays/nc02F/src/host/indexing.jl:17
  getindex(arr::AbstractArray, d::ArrayDomain)
    @ Dagger ~/.julia/packages/Dagger/Mpl5a/src/array/darray.jl:34

The reproducer for this is:

using Dagger, CUDA
A = CUDA.rand(Bool, 64, 64)
DA = DArray(A, Blocks(16, 16))   # ambiguous getindex before fix
collect(DA)

Thanks so much for finding and fixing this! That would be really frustrating to encounter for new GPU users.
