MAINT: Split up the lapack_lite files more sensibly

Also uses this splitting as an excuse to ditch the _lite suffix, in
favor of a f2c_ prefix for all generated files.

Before:

 * `zlapack_lite.c` - Functions for the `complex128` type.
 * `dlapack_lite.c` - Every other lapack function

After:

 * `f2c_z_lapack.c` - Functions for the `complex128` type.
 * `f2c_c_lapack.c` - Functions for the `complex64` type.
 * `f2c_d_lapack.c` - Functions for the `float64` type.
 * `f2c_s_lapack.c` - Functions for the `float32` type.
 * `f2c_lapack.c`   - Every other lapack function
