BaseTools/VfrCompile: Avoid using uninitialized pointer

V2:
Add function _INIT_OPHDR_COND () for variable initialization.
Make code logic more clean.

Previously _CLEAR_SAVED_OPHDR () is used for variable
initialization, and we updated it to clean memory.
But _CLEAR_SAVED_OPHDR () is still called for variable
initialization. This will cause uninitialized pointer
will be checked to free and cause unexpected issue.

This patch is to add new function for variable initialization
and keep _CLEAR_SAVED_OPHDR () to clean memory which is
aligned with its function name.
