Fix corner case in model construction of strings (#3524)

This commit fixes a corner case in the model construction of strings:
For a given length, we were assuming that for each equivalence class, we
could always find an initial guess for a constant to assign to it. This
was not always true, however, because a preceding equivalence class
could use up all constants and get assigned the last remaining one, so
we wouldn't have a constant remaining for the current class. This
resulted in an assertion failure (in debug) or a crash (in production).
This commit fixes the issue by checking whether we've run out of
constants before assigning an initial constant for an equivalence class.

NodeValue: Eliminate redundant NBITS macros. (#3400)

Previously, the metakind header defined macros for the number of bits
reserved for fields in the NodeValue "header" (for the reference count,
the node kind, the number of children and the node id). These macros
were redundant, since the only one using them was the NodeValue itself,
which redefined them (while using them) as constants in the class.
Additionally, MAX_CHILDREN was defined (using these macros) not only
in the metakind header, but redefined in other places.

This commit defines the above values as constexpr members of the
NodeValue class and cleans up redundancy.

This makes the order of theories explicit in the source code rather than relying on the order defined via the build system. Previously, the build system ensured the order of the theories via the KINDS_FILES variable, which is a list of kinds files that is fed to code generation scripts (mkkind, mkmetakind, mkrewriter, mktheorytraits). The generated code critical to the order of theories w.r.t. soundess is the TheoryId enum, and the CVC4_FOR_EACH_THEORY macro. Ideally, we would want to get rid of the latter (ugly and error prone), which is not possible in the current configuration, and to be discussed in the future.
