To make it so that you can pass `freeze: true` to Prism parse
methods and get back a deeply-frozen AST that is Ractor-
shareable.

ruby/ruby measures test coverage of C code, but the `#line` directive
generated by prism points to a file that does not exist, so coverage is
not taken properly.
This changeset specifies the location of the source files as a relative
path in terms of ruby/ruby repo.

- 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

When creating the Ruby AST, we were previously allocating Location
objects for every node and every inner location. Instead, this
commit changes it to pack both the start offset and length into a
single u64 and pass that into the nodes. Then, when the locations
are requested via a reader method, we lazily allocate the Location
objects.

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 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
```

It's possible for us to parse a constant that is invalid in the
current encoding. To fix this, we wrap the intern function in an
rb_protect to ensure we always put a valid symbol into the AST.

Moves the common flag bits to the top. This lets us eliminate the `COMMON`
constant, and also allows us to group encoding flags on a nibble so we
can more easily mask them.
