Switch to manually encoding to fix the build.

Due to the requirement of jscvt feature, a compiler configuration of v8.3 or above is needed to support assembly. Therefore, hand encode is used here instead.

Since we use this define to control the size of our vector data buffers this results in a lot of overhead when we initialise which can be a very noticable problem in emulation, we fill buffers that are orders of magnitude larger than we will ever actually use even with virtual platforms that provide the full range of architecturally supported vector lengths. Define and use the actual architecture maximum to mitigate this.
