Drop MSVC workaround from 2002

(cf. f2b0299972730989c46949d6101c7c346fc01971 "#97095# MS Visual C++ unsigned
__int64 to double missing"), assuming that our baseline MSVC is capable of that
by now.

Replace DOUBLE_SAL_UINT64_MAX with double(SAL_MAX_UINT64) and replace
unsigned_int64_to_double(X) with either X or static_cast<double>(X), matching
respective context.
