util/ifdtool: Add support for checking GPR0 status

This patch adds support for the new command-line option `-c` to
the ifdtool, which is able to check GPR0(Global Protected Range) status.

This patch also add helper function get_enabled_gprd() to get enabled
settings. It's used in enable_gpr0() and is_gpr0_protected().

Developers can use ifdtool with '-c' option to check whether GPR0 is set to
enabled or disabled in the binary file.

BUG=none
TEST=(1) Run `ifdtool -p mtl -c image.bin` on a locked image:
         GPR0 status: Enabled

     (2) Run `ifdtool -p mtl -c unlock_image.bin` on a unlocked image:
         GPR0 status: Disabled

     (3) Run `ifdtool -p mtl -E image-unlocked.bin -O image_lock.bin`
