cmd/compile: fix unified IR panic when expanding nested inline function

Browse source 
When reading body of inlining function, which has another inlined
function in the body, the reader still add this inlined function to
todoBodies, which it shouldn't because the inlined function was read
already.

To fix this, introduce new flag to signal that we are done construting
all functions in todoBodies, thus the addBody shouldn't add anything
to todoBodies then.

Updates #48094
