When an integer constant specified in the .vfr file is
too large for the varstore field it is being used with,
the VFR compiler reports an overflow warning like this:
Test.vfr(693): WARNING: Overflow: Value 1024 is too large to
store in a UINT8
: String to UINT* Overflow
Since Warning does not break the build process,
and it is easy to miss it.
This patch is to update the code to report error and break
the build if meet this kind of issue.

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.

clang generates many warnings
warning: field 'XXX' is uninitialized when used here [-Wuninitialized]
for VfrFormPkg.h.
VfrFormPkg.h defines many classes derived from CIfrObj (along with other
base classes.)
Each of these derived classes defines a non-static member field that serves
as a duplicate pointer to an original pointer defined in the CIfrObj base
class, but cast to a different pointer type.
The derived class constructor passes the duplicate pointer to base class
constructors:
1) Once passes the address of the duplicate pointer to the CIfrObj
constructor to have it initialized.
2) Then passes the duplicate pointer to one or more subsequent base class
constructors to be used.
Both 1) and 2) constitute undefined behavior in C++. C++ prescribes that
base classes are initialized before non-static members when initializing a
derived class. So when base class constructors are executing, it is not
permitted to assume any non-static members of the derived class exist (even
to the stage of having their storage allocated.)
clang does not issue warnings for 1), but issues warnings -Wuninitialized
for 2).
This coding methodology is resolved as follows:
a) The CIfrObj object accessor method for retrieving the original pointer
is revised to a template member function that returns the original
pointer cast to a desired target type.
b) The call to CIfrObj constructor is no longer used to initialize the
duplicate pointer in the derived class.
c) Any subsequent calls to a base class constructor that need to use the
pointer, retrieve it from the CIfrObj base class using the template
accessor method.
d) If the derived class makes no further use of the pointer, then the
duplicate pointer defined in it is eliminated.
e) If the derived class needs the duplicate pointer for other use, the
duplicate pointer remains in the derived class and is initialized in
proper order from the original pointer in CIfrObj.
f) Existing source code that previously used the CIfrObj pointer accessor
method is revised to use the template method.

The member function CVfrDLGLexer::errstd is intended as an override virtual
function of DLGLexerBase::errstd, but due to mismatched prototype, it
didn't override, and never got called.

Enhance VfrCompiler to parse following case:
1. EFI/Buffer VarStore can contain bit fields in their structure.
2. For question Oneof/Checkbox/numeric, their storage can be
bit fields of an EFI VarStore/Buffer VarStore.

1.--autodefault option
VfrCompile will generate default opcodes for questions if some
default are missing.
2 --checkdefault option
VfrCompile will check whether every question has no default or
has all default. If not, will generate an error to let user know
the question misses default.
