lib: crypto: add mscode_parser
In MS authenticode, pkcs7 should have data in its contentInfo field.
This data is tagged with SpcIndirectData type and, for a signed PE image,
provides a image's message digest as SpcPeImageData.
This parser is used in image authentication to parse the field and
retrieve a message digest.
Imported from linux v5.19-rc, crypto/asymmetric_keys/mscode*.
Checkpatch.pl generates tones of warnings, but those are not fixed
for the sake of maintainability (importing from another source).
