command: fix the mode for command "jtag configure"

Before commit 877cec20dc ("command:
check command mode for native jim commands") all the jim commands
were erroneously treated as they had mode COMMAND_ANY.
The commit above fixes the code in order to check the mode and
permit running the commands only if the mode is respected.

Those jim commands that have incorrect mode were not detected nor
fixes because the wrong mode was masked by the missing mode check.
After the commit above, the wrong mode triggers error in several
existing configuration scripts.
A complete list of commands that now does not run anymore as
CONFIG_ANY is reported in ticket 225, but most of them have the
mode set correctly.
At least two instances of command "jtag configure" have the wrong
mode.

Fix the mode to CONFIG_ANY for command "jtag configure" in files
src/jtag/aice/aice_transport.c and src/jtag/tcl.c
