PRISM_SERIALIZE_ONLY_SEMANTICS_FIELDS is set
* Note that we could shift the flags by 2 on serialize & deserialize
but it does not seems worth it as it does not save serialized size
in any significant amount, i.e. average was 0.799 before #2924.
* $ bundle exec rake serialized_size:topgems
Before:
Total sizes for top 100 gems:
total source size: 90207647

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.

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.

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
```

Line numbers may be negative, so we need to introduce signed varint,
so renaming unsigned ones first avoid confusion.

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.
