encoding: avoid quadratic time complexity when json-encoding non-UTF8 strings

Apparently the code uses "+=" with a bytes object, which is linear-time, so the
whole encoding is quadratic-time. This patch makes us use a bytearray object,
instead, which has a(n amortized-)constant-time append operation.

The encoding is still not particularly fast, but at least a 10MB file
takes tens of seconds, not many hours to encode.

test template keywords and functions which require changectx:

  $ hg id -T '{rev} {node|shortest}\n'
  2147483647 ffff
  $ hg id -T '{parents % "{rev} {node|shortest} {desc}\n"}'
  0 cb9a a
  $ hg id -T '{parents}\n'
  cb9a9f314b8b07ba71012fcdbc544b5a4d82ff5b

test nested template: '{tags}'/'{node}' constants shouldn't override the
default keywords, but '{id}' persists because there's no default keyword
for '{id}' (issue5612)

  $ hg id -T '{tags}\n'
  tip
  $ hg id -T '{revset("null:.") % "{rev}:{node|short} {tags} {id|short}\n"}'
