[Bug] Default option is not passed by TVMC Front end

[MNGanesan]

Under Hybrid Target, I have created target specific config or compiler options in the backend(codegen), These option are given with default values too.

Example:

TVM_ROOT/src/relay/backend/contrib/my_target/codegen.cc

struct MyCompilerConfigNode : public tvm::AttrsNode {
String mcpu;

TVM_DECLARE_ATTRS(MyCompilerConfigNode, "ext.attrs.MyCompilerConfigNode") {
TVM_ATTR_FIELD(mcpu)
.describe("CPU type")
.set_default("my_cpu"); <=========
}
};
In the TVMC , I try to access those options under the partition_for_target function

TVM_ROOT/relay/op/contrib/target.py

However, the default values given to these options are not visible.

I doubt TVMC is not handling or honoring the default values for options.

I have no clue if it works for other hybrid target like cmsis-nn or vitis-ai ? Could some put light on this ?
