x86/cpufeatures: Fix various details in the feature definitions
Kept this commit separate from the re-tabulation changes, to make the changes easier to review: - add better explanation for entries with no explanation - fix/enhance the text of some of the entries - fix the vertical alignment of some of the feature number definitions - fix inconsistent capitalization - ... and lots of other small details i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.
