cmd/compile: fix crawling of embeddable types during inline

In CL 327872, there's a fix for crawling of embeddable types directly
reached by the user, so all of its methods need to be re-exported. But
we missed the cased when an un-exported type may be reachable by
embedding in exported type. Example:

	type t struct {}
	func (t) M() {}

	func F() interface{} { return struct{ t }{} }

We generate the wrapper for "struct{ t }".M, and when inlining call to
"struct{ t }".M makes "t.M" reachable.

It works well, and only be revealed in CL 327871, when we changed
methodWrapper to always call inline.InlineCalls, thus causes the crash
in #49016, which involve dot type in inlined function.

Fixes #49016
