Dan Scales 1760d736f6 [dev.regabi] cmd/compile: exporting, importing, and inlining functions with OCLOSURE
I have exporting, importing, and inlining of functions with closures
working in all cases (issue #28727). all.bash runs successfully without
errors.

Approach:
  - Write out the Func type, Dcls, ClosureVars, and Body when exporting
    an OCLOSURE.

  - When importing an OCLOSURE, read in the type, dcls, closure vars,
    and body, and then do roughly equivalent code to (*noder).funcLit

  - During inlining of a closure within inlined function, create new
    nodes for all params and local variables (including closure
    variables), so they can have a new Curfn and some other field
    values. Must substitute not only on the Nbody of the closure, but
    also the Type, Cvars, and Dcl fields.

Fixes #28727
