`to_power_type` does not exist any more in `Base`

[nsajko]

The to_power_type function doesn't exist any more in Julia Base since PR JuliaLang/julia#58720. I suppose that will break loading of AMDGPU because of this block:

AMDGPU.jl/src/array.jl

Lines 305 to 311 in f8ce052

	if VERSION ≥ v"1.12-"
	# TODO is this OK to do this?
	# Use type inference for x^p instead of `promote` which does `x * x`.
	function Base.to_power_type(x::AnyROCArray)
	convert(Base._return_type(*, Tuple{typeof(x), typeof(x)}), x)
	end
	end
