Reduce invalidation by not specializing lastindex/axes1

[jishnub]

I don't see any speedup from specializing these on recent Julia versions, and this PR reduces invalidation. On master (Julia v1.8.2)

julia> r = OffsetArrays.IdOffsetRange(3:10000);

julia> @btime firstindex($(Ref(r))[]);
  2.935 ns (0 allocations: 0 bytes)

julia> @btime lastindex($(Ref(r))[]);
  3.354 ns (0 allocations: 0 bytes)

This PR

julia> @btime firstindex($(Ref(r))[]);
  2.935 ns (0 allocations: 0 bytes)

julia> @btime lastindex($(Ref(r))[]);
  2.942 ns (0 allocations: 0 bytes)

Similarly, for axes1. On Julia v1.9, and using the master branch for OffsetArrays:

julia> using SnoopCompileCore

julia> invalidations = @snoopr using OffsetArrays;

julia> using SnoopCompile

julia> trees = invalidation_trees(invalidations)

We may reduce another set of invalidation by not specializing Base.axes1 for IdOffsetRange, which seems redundant as well on recent Julia versions.
