cmd/compile: make funccompile non-reentrant

Currently, there's awkward reentrancy issue with funccompile:

    funccompile -> compile -> dtypesym -> geneq/genhash/genwrapper -> funccompile

Though it's not a problem at this moment, some attempts by @mdempsky to
move order/walk/instrument into buildssa was failed, due to SSA cache

This commit fixes that reentrancy issue, by making generated functions
to be pumped through the same compile workqueue that normal functions
are compiled. We do this by adding them to xtop, instead of calling
funccompile directly in geneq/genhash/genwrapper. In dumpdata, we look
for uncompiled functions in xtop instead of compilequeue, then finish
compiling them.

Updates #38463
Fixes #33485
