[202405] ImageValidation.py: Don't parse entire image

[Javagedes]

Description

This commit modifies the PE parsing functionality to only parse the headers of the image, rather than the entire image. This change is made to improve performance and also the probability of failing to parse the entire image. This comes after this commit (https://github.com/erocarrera/pefile/pull/365) in pefile resulted in efi image parsing failures, breaking the build.

This commit also wraps the parsing of the image in a try-except block to catch any exceptions that may be raised during parsing, to cleanly exit.

See: https://github.com/microsoft/mu_tiano_platforms/pull/1025 and https://github.com/erocarrera/pefile/issues/421

Straight to edk2? I'm good to take this here too, so we aren't broken, of course. Or has this plugin not gone upstream?
