* This is also faster than calling pm_encoding_utf_8_alpha_char/pm_encoding_utf_8_alnum_char
as those compute the character width and do extra checks.

Ensure we don't accidentally parse the symbol encoding twice, and
ensure we parse it in every circumstance we need to by requiring
it as a parameter.

Ruby sets a Symbol literal's encoding to US-ASCII if the symbols consists only of US ASCII code points. Character escapes can also lead a Symbol to have a different encoding than its source's encoding.

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.

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.

The previous implementation of hash deopt was based on clearing the static literal flag on a hash node if the element that was being added was an array, hash or range node, or if the element was not a static literal in the first place.
However, this is not correct. First of all, the elements added to a hash node will primarily be assoc nodes, but never array, hash or range nodes. Secondly, the static literal flag is set on assoc nodes, only if the value in an assoc node is a static literal, so the key is never checked. As a result, the static literal flag on a hash node would never be cleared if the key wasn't a static literal.
This commit fixes this by clearing the static literal flag if:
1. the element is not an assoc node,
2. the element is an assoc node, but the key is not a static literal, or
3. the element is an assoc node, the key is a static literal, but assoc node (and thus the value in assoc node) is not a static literal.
