Move annotation's thread_local storage to .cc file and clean up dependencies to avoid a duplicate symbol error.

There are currently several different terms used to refer to a parent IR unit in 'get' methods: getParent/getEnclosing/getContaining. This cl standardizes all of these methods to use 'getParent*'.

In declarative rewrite rules, a symbol can be bound to op arguments or
results in the source pattern, and it can be bound to op results in the
result pattern. This means given a symbol in the pattern, it can stands
for different things: op operand, op attribute, single op result,
op result pack. We need a better way to model this complexity so that
we can handle according to the specific kind a symbol corresponds to.

Created SymbolInfo class for maintaining the information regarding a
symbol. Also created a companion SymbolInfoMap class for a map of
such symbols, providing insertion and querying depending on use cases.

By default, all functions are exported including main. This flag will be used to support new use cases like conversion of speech models to tflite where we want to run specific inference graphs through the converter and export specific functions (e.g. Joint, Encoder etc.) to a separate flatbuffer.

Avoid diamond inheritance in tablegen with classes that inherit from Op and also inherit from Results and Arguments.
Remove extraneous Operand and Result names in cases where there's only one. There will already be a generated getOperand/getResult method. Having an additional "res" accessor doesn't add value.
In places where naming a single result is necessary for traits that check directly against attribute names, named single results "result".
Avoid non-elementwise ops inheriting from elementwise subclasses.

Currently, GrpcServer does not support clean shutdown and destruction after GrpcServer::Start() is called, and logs a FATAL error in this case. In UpdateTFE_ContextWithServerDef(), there are several cases where a method can fail (e.g. due to invalid user input), and we attempt to destroy the created GrpcServer before returning. By deferring the call to GrpcServer::Start(), we can return an error to the client without crashing their process.
