PETSc failure on Windows with Julia 1.4+

Not sure what is going on, but this fails on GitHub Actions CI:

in expression starting at D:\a\PETSc.jl\PETSc.jl\src\lib.jl:30
PetscInitialize at C:\Users\runneradmin\.julia\artifacts\11ff68d5ef73bd715cf1d2ac322a742f0bd2bbfa\bin\libpetsc.dll (unknown line)
PetscInitializeNoArguments at C:\Users\runneradmin\.julia\artifacts\11ff68d5ef73bd715cf1d2ac322a742f0bd2bbfa\bin\libpetsc.dll (unknown line)

https://github.com/JuliaParallel/PETSc.jl/pull/99/checks?check_run_id=1038527677#step:6:38

To replicate, use

using PETSc
function initialize()
  ccall((:PetscInitializeNoArguments, libpetsc), Cint, ())
end

The latest build (#3249) seems to work with Julia 1.6: JuliaParallel/PETSc.jl#148
