Split up the diagnostic levels so that error and warning levels
aren't mixed. Also fix up deconstruct_keys implementation.

It's possible to repeat parameters in method definitions like so:
```ruby
def foo(_a, _a)
end
```
The compiler needs to know to adjust the local table size to account for
these duplicate names. We'll use the repeated parameter flag to account
for the extra stack space required

Because this is a user-facing change, we also need to deal with the
fact that CRuby 3.3.0 was just released.
In order to support workflows that want to parse exactly as CRuby
parses in a specific version, this PR introduces a new option to
the options struct that is "version". This allows you to specify
that you want "3.3.0" parsing.
I'm not sure if this is the correct solution. Another solution is
to just fork and keep around the old branch for security patches.
Or we could keep around a copy of the source files within this
repository as another directory and only update when necessary.
There are a lot of potential solutions here.
Because this change is so small and the check for it is so minimal,
I've decided to go with this enum. If this ends up entirely
cluttering the codebase with version checks, we'll come up with
another solution. But for now this works, so we're going to go in
this direction for a bit until we determine it's no longer working.

A lot of tools use Ripper/RubyVM::AbstractSyntaxTree to determine
if a source is valid. These tools both create an AST instead of
providing an API that will return a boolean only.
This new API only creates the C structs, but doesn't bother
reifying them into Ruby/the serialization API. Instead it only
returns true/false, which is significantly more efficient.

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.

The problem was deeper than just looking back a single token.
You can push the heredoc_end token way back into the list.
We need to save the last location of a heredoc end to see if
it's the last token in the file.

Fundamentally, `foo { |bar,| }` is different from `foo { |bar, *| }`
because of arity checks. This PR introduces a new node to handle
that, `ImplicitRestNode`, which goes in the `rest` slot of parameter
nodes instead of `RestParameterNode` instances.
This is also used in a couple of other places, namely:
* pattern matching: `foo in [bar,]`
* multi target: `for foo, in bar do end`
* multi write: `foo, = bar`
Now the only splat nodes with a `NULL` value are when you're
forwarding, as in: `def foo(*) = bar(*)`.

* The same order as in source code.
* CallOrWriteNode, CallOperatorWriteNode, CallAndWriteNode already have
the correct order so it was also inconsistent with them.

librubyparser was an artifact of the prototype that was initially
named ruby-parser. Instead, this renames it to libprism to be
consistent with the actual name.
