Ensure sufficient size of variables used for module+submodule names.

PR fortran/93486
* module.c: Increase size of variables used to read module names
when loading interfaces from module files to permit cases where
the name is the concatenation of a module and submodule name.
* gfortran.dg/pr93486.f90: New test.

--- Comment #2 from Andrew Benson  ---
The problem is caused when loading (generic or operator) interfaces from a
module file. The module name can include the submodule name, so a size of
2*GFC_MAX_SYMBOL_LEN+2 is required to read this in.

The attached patch fixes this problem.
