gsctool: Add AP RO verify write protect descriptors config command

This patch adds the ability to get and set the AP RO verification
write protect descriptors registers from `gsctool` by adding a new `-E`
command flag with an optional argument.

BUG=b:250972056
TEST=Running gsctool locally to set and get the write protect
     descriptors to verify communication and handlers are working
     properly:

    $ gsctool -D -E
    ...
    not provisioned
    $ gsctool -D -E "0xff 0xf"
    ...
    expected values: 1: ff & 0f
    $ gsctool -D -E "ff 0f f"
    ...
    Invalid the write protect descriptors hex string length
    $ gsctool -D -E "ff f 0x00 ff"
    ...
    $ gsctool -D -E
    ...
    expected values: 1: ff & 0f, 2: 00 & ff
    $ gsctool -D -E "0xff 0xf 0x00 0xff 0xf0 f0"
    ...
    $ gsctool -D -E
    ...
    expected values: 1: ff & 0f, 2: 00 & ff, 3: f0 & f0
