This PR is the first step in replacing options access via options::foo() to using the environment (via EnvObj and options().module.foo). It replaces all such options accesses in the preprocessing passes.

Similar to #6031, this PR implements suggestions from iwyu to reduce the number of includes in header files by introducing forward declarations and moving includes to source files.

Fixes #5163. When `:global-declarations` is disabled (the default), then
`(reset-assertions)` should remove all declared and defined symbols. Before
this commit, we would remove the defined function from `SmtEngine` but the
parser would not remove it from its symbol table because the symbol was defined
at (what it considered) level 0. Level 0, however, is reserved for global
symbols that we never want to remove.
This commit adds an additional global `pushScope()`/`popScope()`, similar to
what we have in `SmtEngine`. As a result, user-defined symbols are now defined
at level 1 and get removed from the `SymbolTable` when `(reset-assertions)` is
called. The commit also makes sure that symbols defined by the logic are
asserted at level 0, so that they are not removed by `(reset-assertions)`. It
adds a flag to `defineType` to ignore duplicate definitions because some
symbols are defined by multiple logics, which leads to a failing assertion when
inserting them both at level 0 in the hashmap of the `SymbolTable`. E.g.
strings and integer arithmetic both define `Int`. The commit also fixes
existing unit tests that fail with these stricter semantics of
`(reset-assertions)`.

This PR updates the update-copyright.pl script to also update/add copyright headers to CMake specific files. It further fixes a small typo in the header.
