Unfortunately, if I remove importlib("stdole2.tlb"), generated .tlb seems
rejected to register into Windows COM+ Catalog.

Wine has stdole2.tlb in its fakedlls directory, but widl does not accept
this by

  error: Wrong or unsupported typelib magic 405a4d

Even if I copied native stdole2.tlb, widl fails with the same error.

Do you have any idea about this error?

No, I suggest you ask on the Wine mailing lists.  In the meanwhile we
can include a precompiled .tlb file in the QEMU repository and use midl.

Seems like your tlb has nonstandard identifying characters. Check first
several bytes of the tlb file. Usually it should be something like '4D
53 46 54', or '4D 5A 90'

I found '4D 53 46 54' at offset 0x300 of stdole2.tlb.
Wine's stdole2.tlb also have the signature at offset 0x738.

(might have an additional header before the main part?)

Widl accepted the wine's stdole2.tlb when I removed the header,
but still, the generated qga-provider.tlb was not accepted by Windows...:(

I will take this way so far.

I rechecked stdole2.tlb provided by MS. All three versions (arm, x86,
and x64) begin with 'MSFT' (4D 53 46 54) and have 00 00 00 00  at offset
0x300

Oops, I was watching stdole2.tlb picked up from system32 directory.
Thank you for rechecking.

Still, it is not available in POSIX environment...
