[ruby/prism] Finish keyword hash node flag refactor by renaming flag

[ruby/prism] Fix the implementation of the flag on keyword hash nodes

2023-12-14T18:05:54+00:00

The previous implementation was incorrect since it was just checking for all keys in assoc nodes to be static literals but the actual check is that all keys in assoc nodes must be symbol nodes.

This commit fixes that implementation, and, also, aliases the flag to `PM_KEYWORD_HASH_NODE_FLAGS_SYMBOL_KEYS` so that ruby/ruby can start using the new flag name.

I intend to later change the real flag name to `PM_KEYWORD_HASH_NODE_FLAGS_SYMBOL_KEYS` and remove the alias.

[ruby/prism] Change numbered parameters

2023-12-01T17:03:09+00:00

Previously numbered parameters were a field on blocks and lambdas
that indicated the maximum number of numbered parameters in either
the block or lambda, respectively. However they also had a
parameters field that would always be nil in these cases.

This changes it so that we introduce a NumberedParametersNode that
goes in place of parameters, which has a single uint8_t maximum
field on it. That field contains the maximum numbered parameter in
either the block or lambda.

As a part of the PR, I'm introducing a new UInt8Field type that
can be used on nodes, which is just to make it a little more
explicit what the maximum values can be (the maximum is actually 9,
since it only goes up to _9). Plus we can do a couple of nice
things in serialization like just read a single byte.

[ruby/prism] Convert start line to signed integers

2023-11-29T13:56:19+00:00

Ruby allows for 0 or negative line start, this is often used
with `eval` calls to get a correct offset when prefixing a snippet.

e.g.

```ruby
caller = caller_locations(1, 1).first
class_eval <<~RUBY, caller.path, caller.line - 2
  # frozen_string_literal: true
  def some_method
    #{caller_provided_code_snippet}
  end
RUBY
```
