feat(javascript): Refactor & Compress Long

[theweipeng]

Refactor the code generator

1. Currently, JavaScript can only register a Object by Type.object, because the generator is too simple
2. Primitive generator of types like string、number can't be inlined in the holder collection, which cause necessary polymorphic that affect the performance

Enhancement performance

1. Currently, Buffer.latin1Slice would transfer from native code generated by JIT to v8 runtime, This has a significant impact on performance, so we use String.fromCharCode to create little string when the string length is less than 15. It is a magic number, but I have tested it and it works fine.

Improve

When useSliceString is disabled, the performance of deserialization improves by 100%. It is 3 times faster than native JSON and twice as fast as protobuf.

When useSliceString is enabled, the performance of deserialization improves by 30%. It is 5 times faster than native JSON and 3 times faster than protobuf.

Before:

Disable useSliceString

Enable useSliceString

After:

Disable useSliceString

Enable useSliceString

@bytemain Hi, could you please take a review, It remove the limit which mentioned in #1304

[bytemain]

it seem that this is not a problem, all the call will happen in this closure

---

I checked the snapshot and donot sure is this a problem?

[bytemain]

fantasitic work, this is the thing I wanted of a serialization framework

This is not a problem, but declare the readInner before the read is better. I will change it

I think you can copy some test case in the #1304:

• https://github.com/apache/incubator-fury/pull/1304/files#diff-9d33aa5fce03357373ad7c54b9636452600284f3e7153064438e277158a3e9cfR60

Looks good to me, but has some typo.

And we can improve the style of generated code, this can be done in further

I fixed it and added an afterCodeGenerated hook to allow users to format the code. Formatting is not a default action, as I believe we should keep things simple and avoid including too many dependencies.
