handle tinfo_t() exception when ctor not supported

[tarterp]

ida_typeinf.tinfo_t(new_type, None, ida_typeinf.PT_SIL) throws an exception with various versions of IDA.

new_tinfo_t expected at most 1 arguments, got 3
Additional information:
Wrong number or type of arguments for overloaded function 'new_tinfo_t'.
  Possible C/C++ prototypes are:
    tinfo_t::tinfo_t()
    tinfo_t::tinfo_t(type_t)
    tinfo_t::tinfo_t(tinfo_t const &)

I believe this was fixed in IDA 9.0 SP1. Below is a table of versions I was able to test on.

	8.40	8.50	9.00	9.0 SP1	9.10
win32	❌	✅	❌	❓	✅
linux	❌	❓	❌	✅	✅

A workaround is to create an empty type with ida_typeinf.tinfo_t() and then create the type with ida_typeinf.parse_decl(). This requires adding a semicolon to the type or it will fail.
