Depended types' encoder functions are not all computed during pretouch

[bimoadityar]

See #838 for background. In particular, the provided example code has no dynamic interface and all the depended types should be able to be introspected using reflection.

I see the issue may be a bug in the encoder pretouchType implementation. See encoder's pretouchTypeX86 and pretouchTypeVM. It creates a compiler, but does not do anything with it, making the function always return an empty map. Compare it to the working decoder's JIT pretouchType and VM pretouchType, which use the compiler in the passed decoder functions.

try pretouch *StructXX and Struct both?

Because I am a library maintainer, if I want to manually pretouch all the depended types, I will need to introspect the types by myself, which is not ideal because sonic already does this where which types need their own encoder functions depend on the sonic internal logic of inline depths.

Try SetMaxInlineDepth=1 and RecursiveDepth=100 ?

I think liuq gave similar suggestion, but I do not see it working on my local.
