with #133413 the intent was that VSE Text strips would not use the fallback font stack if using a custom (non-default) font. However this determination was done by comparing the font id. This was very weak as the id can vary quite a bit within the first few fonts. This PR instead adds a BLF function (BLF_is_builtin) that uses BLF_DEFAULT font flag instead.
