Cuong Manh Le e99f285d52 cmd/compile: fix ICE when checking implicit dot for method call
CL 414836 limited the check for implicit dot for method call enabled by
a type bound. However, the checking condition for ODOTMETH only is not
right. For example, for promoted method, we have a OXDOT node instead,
and we still have to check for implicit dot in this case.

However, if the base type and embedded types have the same method name,
e.g in issue #53419, typecheck.AddImplicitDots will be confused and
result in an ambigus selector.

To fix this, we ensure methods for the base type are computed, then only
do the implicit dot check if we can find a matched method.

Fixes #54348
