color: stop mutating the default effects map

A future change will make color.setup() callable a second time when the pager is
spawned, in order to honor the 'color.pagermode' setting.  The problem was that
when 'color.mode=auto' was resolved to 'win32' in the first pass, the default
ANSI effects were overwritten, making it impossible to honor 'pagermode=ansi'.
Also, the two separate maps didn't have the same keys.  The symmetric difference
is 'dim' and 'italic' (from ANSI), and 'bold_background' (from win32).  Thus,
the update left entries that didn't belong for the current mode.  This bled
through `hg debugcolor`, where the unsupported ANSI keys were listed in 'win32'
mode.

As an added bonus, this now correctly enables color with MSYS `less` for a
command like this, where pager is forced on:

    $ hg log --config color.pagermode=ansi --pager=yes --color=auto

Previously, the output was corrupted.  The raw output, as seen through the ANSI
blind `more.com` was:

    <-[-1;6mchangeset:   34840:3580d1197af9<-[-1m
    ...

which MSYS `less -FRX` rendered as:

    1;6mchangeset:   34840:3580d1197af91m
    ...

(The two '<-' instances were actually an arrow character that TortoiseHg warned
couldn't be encoded, and notepad++ translated to a single '?'.)

Returning an empty map for 'ui._colormode == None' seems better that defaulting
to '_effects' (since some keys are mode dependent), and is better than None,
which blows up `hg debugcolor --color=never`.
