tr2: avoid to print "interesting" config repeatedly

Changes since v4:

By Jeff Hostetler's suggestion, we can use GIT_TRACE2_CONFIG_PARAMS and trace2.configparams to dump "interesting" config values to the trace2 log. So I drop the commit [5/5] 'bitmap: add trace2 outputs during open "bitmap" file' in v4.

Then I found if a config key exist multiple config values in different scope the trace2 log will print the value repeatly but not only print the final active value, so a new commit "avoid to print "interesting" config repeatedly" is appended in v5.

Finally, compared with [3/5] in v4, commit "pack-bitmap.c: retrieve missing i18n translations" fix every place which was missing translation in pack-bitmap.c.

Thanks.
