An explicit `false` is not equivalent to the comment being missing,
because the default can be switched with a runtime flag:
```bash
$ ruby --enable-frozen-string-literal -e 'p "foo".frozen?'
true
```

- Add `x` prefix to malloc, calloc, realloc, and free
(eg: malloc -> xmalloc)
- By default, they are replaced with stdlib's functions at build
- You can use custom functions by defining `PRISM_CUSTOM_ALLOCATOR` macro

This PR fixes following error when using `version: latest` argument.
```console
$ ruby -rprism -e "p Prism.parse('-> { it }', version: 'latest')"
-e:1:in `parse': invalid version: latest (ArgumentError)
p Prism.parse('-> { it }', version: 'latest')
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
from -e:1:in `<main>'
```
The argument `version: latest` in the added test is commented as potentially being
better replaced with `version: 3.4.0` in the future.

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.

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
