SecurityPkg/DxeImageVerificationLib: Disable SHA1 base on MACRO

Browse Source 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2943

Disable SHA1 base on the MACRO DISABLE_SHA1_DEPRECATED_INTERFACES.
SHA1 is deprecated function and the MACRO is used to remove the whole
implementation of the SHA1. For the platforms that do not need SHA1
for security, the MACRO should works for DxeImageVerificationLib as
well.
