Gautam Gala 2d86117167 rust/pvimg: SE header tampering tool for use with tests ...

Adding a new tool (tamper_pvimg) for helping to test if the expected
RC and RRC values are received for several different reasons when
DIAG 308 subcode does not complete successfully. The reasons can include
issues related to host key hash, SE header, ALD/PDL/TLD mistmatch, etc.

This tool can read the SE image and manipulate one of the SE header
fields so that the SE image will fail to enter secure mode during the
stage3a booting process. The stage3a bootloader should receive UVC
command code id, RC and RRC values corresponding to the SE header
field that was manipulated. These values will be checked for
consistency in the tests for correctness of DIAG 308 subcode 10 RCs
and RRCs.
