fix invalidations from loading Static.jl

[ranocha]

I improved type stability of two methods to fix some invalidations. This is based on the following code:

julia> using Pkg; Pkg.activate(temp=true); Pkg.add("ArrayInterface")

julia> using SnoopCompileCore; invalidations = @snoopr(using ArrayInterface); using SnoopCompile

julia> trees = invalidation_trees(invalidations)
...
inserting (::Colon)(L::Integer, ::Static.StaticInt{U}) where U in ArrayInterface at ~/.julia/packages/ArrayInterface/eITVf/src/ranges.jl:157 invalidated:
...
inserting (::Colon)(::Static.StaticInt{L}, U::Integer) where L in ArrayInterface at ~/.julia/packages/ArrayInterface/eITVf/src/ranges.jl:158 invalidated:
