Resolves: tdf#160985 Max integer representation for rtl_math_StringFormat_G

Same as for rtl_math_StringFormat_Automatic we want to preserve
the highest accuracy of integer values also with
rtl_math_StringFormat_G if nDecPlaces is large enough, instead of
possibly rounding into 15 digits. This occurred with
FastSaxSerializer::write(double) but rtl::OString::number(double)
and rtl::OUString::number(double) and rtl_math_doubleToString()
and rtl::str::valueOfFP() and rtl_str_valueOfDouble() and all
places calling with rtl_math_StringFormat_G are similar affected.

Question might remain why those places use
rtl_math_StringFormat_G with fixed nDecimalPlaces calculated from
RTL_STR_MAX_VALUEOFDOUBLE - SAL_N_ELEMENTS("-x.E-xxx") + 1
instead of rtl_math_StringFormat_Automatic with
rtl_math_DecimalPlaces_Max.
