Amaan Qureshi 74b7d0c951 feat!: add an eof function 
This commit adds an `eof()` function for grammars, which is easier to
use than the NUL byte directly. It compiles down to a constraint that
the enclosing production can only reduce at end of input, not to a
shiftable token.

BREAKING CHANGE: Public error types for `tree-sitter-generate` were modified.

These small grammars demonstrate specific features or test for certain specific regressions.

For some of them, compilation is expected to fail with a given error message. For others, the resulting parser is expected to produce certain trees.
