Fix the format of some doc.odin files of the core library which did not made into the documentation.

`c/frontend/tokenizer`:
   add proper "Example:" header to demo example code,
   removed empty lines.
`container/bit_array`:
   moved comment before package;
   aligned narrative lines to left margin;
   converted case lines into bulleted lines ("- ");
   converted individual examples to single-tab-indented preformatted text.
`dynlib`:
   removed "//+build ignore" line;
   added newline at EOF.
`image/netpmb`:
   converted indented lines of "Reading", "Wrting" and "Some syntax..." into bulleted lists;
   "Formats" indented lines kept as they are as the preformatted text seems relevant to keep the alignments;
   doubly indented lines kept as single-indented to keep them different (as the format does not allow for two-level bulleted lists);
   removed empy lines.
`os/os2`:	WIP, not modified
`sys/info`:
   removed "//+build ignore" line;
   converted tab-indented initial description into regular left-margin comment;
   moved uncommented sample code within the doc comment as an "Example:";
   moved simple- and double-tabbed separate comments with sample Windows and macOS outputs within the doc comment as bulleted headlines with preformatted output listings;
   removed now empty comments and blank lines after the package line.
`text/i18n`:
   removed "//+build ignore" line;
   moved the pacakge line at the end;
   de-indented the tab-indented introductory narrative;
   moved sample code comments into the doc comment as tab-indented code with a proper "Example:" heading;
   removed "```" MD attempts at code formatting.
`text/table`:
   unindented the comment lines of a descriptive kind;
   headlines of major subdivisions are marked as bold;
   kept code samples as tab-indented preformatted text (as there are several of them, the standard "Example:" and "Output:" headings cannot be used) removing the "```" MD attempts at code formatting;
   removed in-between blank lines.
