[flang] Implement derived type description table encoding Define Fortran derived types that describe the characteristics of derived types, and instantiations of parameterized derived types, that are of relevance to the runtime language support library. Define a suite of corresponding C++ structure types for the runtime library to use to interpret instances of the descriptions. Create instances of these description types in Semantics as static initializers for compiler-created objects in the scopes that define or instantiate user derived types. Delete obsolete code from earlier attempts to package runtime type information. Differential Revision: https://reviews.llvm.org/D92802

[flang] Implement STORAGE_SIZE(), SIZEOF(), C_SIZEOF() STORAGE_SIZE() is a standard inquiry intrinsic (size in bits of an array element of the same type as the argument); SIZEOF() is a common extension that returns the size in bytes of its argument; C_SIZEOF() is a renaming of SIZEOF() in module ISO_C_BINDING. STORAGE_SIZE() and SIZEOF() are implemented via rewrites to expressions; these expressions will be constant when the necessary type parameters and bounds are also constant. Code to calculate the sizes of types (with and without alignment) was isolated into Evaluate/type.* and /characteristics.*. Code in Semantics/compute-offsets.* to calculate sizes and alignments of derived types' scopes was exposed so that it can be called at type instantiation time (earlier than before) so that these inquiry intrinsics could be called from specification expressions.
