Make order of theories explicit in the source code. (#3379)
Fixes #2517.
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.

Fix off by one error in strings flat form explanation (#3273)
Fixes #3272.
This was caused by not explaining the last equal component in a flat form inference. For example, if `x=y`, we may infer `z=""` from `u++x++z=u++y` since the 1st and 2nd components of these strings are equal. However, we would not add the explanation of `x=y` due to an off-by-one error.
Notice that this code is very rarely used (the code for F_EndpointEmp is not covered by our regressions). This is since length elaboration should catch conflicting cases like above, where `len(u++x++z)!=len(u++y)` if `x=y` and `z!=""` and thus `u++x++z != u++y`. #3272 happened to catch a rare case where it is applied. This is likely due to theory combination not propagating an equality prior to running a full effort call to strings check, which is unexpected but not impossible.
