indirectly recursive cycles.
This can cause infinite loops in the parser near EOF.

When a *named* rule in the extras is able to match the empty string,
parsing can hang in certain situations (i.e. near EOF).

- Use `globalThis` for `reserved` function export
- Add `reserved` field and function to DSL declarations
- Add `reserved` rule to grammar schema

As the call to `symbol_is_used` does not depend
on the production, it is more efficient to call it
only once outside the loop over productions.
I'm not sure if `rustc` is able to do this optimization
on its own (it would need to know that the function
is pure, which sounds difficult in general).

The period was dropped in the `thiserror` refactor
(79444e07f9), which caused the
`test_flatten_grammar_with_recursive_inline_variable` test to fail.

This reverts commit dc4e232e6e.
Reason: The sha in the generated output (which most distro builds of
tree-sitter, including `cargo install`, strip) produces too many
conflicts when verifying via CI that parsers are regenerated on every
grammar change.

Improve the `NonTokenReservedWord` error message by including the
specific reserved word that was not used as a token.

This makes `parser.c` follow the https://generated.at/ convention for generated files. This potentially allows any compatible IDE to discourage editing it directly.

Problem: Linking different parsers into one executable fails due to duplicate symbols.
Solution: Mark `TSCharacterRange` as `static` when generating parsers.
fixes#4209
(cherry picked from commit 8138dba800)
Introduces a new function that takes in a supertype symbol and returns
all associated subtypes. Can be used by query.c to give better errors
for invalid subtypes, as well as downstream applications like the query
LSP to give better diagnostics.
