- 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 implements proper file parsing error handling. Previously
`file_options` would call `pm_string_mapped_init` which would print an
error from `perror`. However this wouldn't raise a proper Ruby error so
it was just a string output. I've done the following:
- Raise an error from `rb_syserr_fail` with the filepath in
`file_options`.
- No longer return `Qnil` if `file_options` returns false (because now
it will raise)
- Update `file_options` to return `static void` instead of `static
bool`.
- Update `file_options` and `profile_file` to check the type so when
passing `nil` we see a `TypeError`.
- Delete `perror` from `pm_string_mapped_init`
- Update `FFI` backend to raise appropriate errors when calling
`pm_string_mapped_init`.
- Add tests for `dump_file`, `lex_file`, `parse_file`,
`parse_file_comments`, `parse_lex_file`, and `parse_file_success?`
when a file doesn't exist and for `nil`.
- Updates the `bin/parse` script to no longer raise it's own
`ArgumentError` now that we raise a proper error.
Fixes: ruby/prism#2207b2f7494ff5
Split up the diagnostic levels so that error and warning levels
aren't mixed. Also fix up deconstruct_keys implementation.

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.

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

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.
