Fix Base.precision on Julia v1.11

[jondeuce]

A recent bugfix on Julia master renamed Base._precision(T) (without a second base argument) to Base._precision_with_base_2(T), which broke precision(Double64). This PR patches that.

Before this PR:

julia-1.10.0> using DoubleFloats

julia-1.10.0> precision(Double64)
106

julia-1.11.0-DEV.1459> precision(Double64)
ERROR: MethodError: no method matching _precision_with_base_2(::Type{Double64})

Closest candidates are:
  _precision_with_base_2(::BigFloat)
   @ Base mpfr.jl:957
  _precision_with_base_2(::Type{BigFloat})
   @ Base mpfr.jl:962
  _precision_with_base_2(::Type{Float64})
   @ Base float.jl:841
  ...

Stacktrace:
 [1] _precision(x::Type, base::Int64)
   @ Base ./float.jl:844
 [2] precision(::Type{Double64}; base::Int64)
   @ Base ./float.jl:847
 [3] precision(::Type{Double64})

   @ REPL[1]:1

After this PR:

julia-1.11.0-DEV.1459> using DoubleFloats

julia-1.11.0-DEV.1459> precision(Double64)
