Check for out of range values in CPDF_SimpleFont::LoadSubstFont()

The font weight value returned by CPDF_Font::GetFontWeight() is inferred
from the /StemV value, which may be outside the normal range of expected
values. Check for this is CPDF_SimpleFont::LoadSubstFont() and treat
out-of-range values like std::nullopt - fall back to the normal font
weight.
