- Add "using namespace mlir::tblgen" in several of the TableGen/*.cpp files and
eliminate the tblgen::prefix to reduce code clutter.
Differential Revision: https://reviews.llvm.org/D85800
Summary: This revision adds support for specifying operands or results as "optional". This is a special case of variadic where the number of elements is either 0 or 1. Operands and results of this kind will have accessors generated using Value instead of the range types, making it more natural to interface with.

Certain ops can have multiple variadic operands/results, e.g., `tf.DynamicStitch`.
Even if an op has only one variadic operand/result, it is not necessarily the
very last one, e.g., `tf.RaggedGather`. This CL enhances TableGen subsystem to be
able to represent such cases.
In order to deduce the operand/result value range for each variadic operand,
currently we only support variadic operands/results all of the same size.
So two new traits, `SameVariadicOperandSize` and `SameVariadicResultSize` are
introduced.

Now, op attribute names don't have '.' in their names so the special handling for it
can be removed. Attributes for functions still have dialect prefix with '.' as separator but TableGen does not deal with functions.
TESTED with existing unit tests

Previously Value was a pair of name & Type, but for operands/result a TypeConstraint rather then a Type is specified. Update C++ side to match declarative side.

We specify op operands and results in TableGen op definition using the same syntax.
They should be modelled similarly in TableGen driver wrapper classes.
