[PETSc] Upgrades petsc to 3.15.2 and enables multiple precision, scal…

…ar, and int types (JuliaPackaging#3249)

* [PETSc] Update PETSc version

* [PETSc] Add `-fno-stack-protector` flag

* [PETSc] Fix MPI library path

* [PETSc] Require GCC 9 for libgfortran5

The linker that comes with GCC 8 emits a warning on `{i686,x86_64}-linux-musl` and that makes configuration script fail.

* [PETSc] Add build with multiple types

 - Real and Complex
 - Int32 and Int64
 - Float64 and Float32

* [PETSc] Delete duplicated PETSc.pc file
