This is a full audit of emitError calls, I took the opportunity
to remove extranous parens and fix a couple cases where we'd
generate multiple diagnostics for the same error.

We currently restrict parsing of location to not allow nameloc being
nested inside nameloc. This restriction may be historical as there
doesn't seem to be a reason for it anymore (locations like this can be
constructed in C++ and they print fine). Relax this restriction in the
parser to allow this nesting.

Lots of custom ops have hand-rolled comma-delimited parsing loops, as does
the MLIR parser itself. Provides a standard interface for doing this that
is less error prone and less boilerplate.
While here, extend Delimiter to support <> and {} delimited sequences as
well (I have a use for <> in CIRCT specifically).

This also exposed a bug in Dialect loading where it was not correctly identifying identifiers that had the dialect namespace as a prefix.

This revision adds support in the parser/printer for "deferrable" aliases, i.e. those that can be resolved after printing has finished. This allows for printing aliases for operation locations after the module instead of before, i.e. this is now supported:
```
"foo.op"() : () -> () loc(#loc)
#loc = loc("some_location")
```

Locations often get very long and clutter up operations when printed inline with them. This revision adds support for using aliases with trailing operation locations, and makes printing with aliases the default behavior. Aliases in the trailing location take the form `loc(<alias>)`, such as `loc(#loc0)`. As with all aliases, using `mlir-print-local-scope` can be used to disable them and get the inline behavior.

Summary: At this point Parser has grown to be over 5000 lines and can be very difficult to navigate/update/etc. This commit splits Parser.cpp into several sub files focused on parsing specific types of entities; e.g., Attributes, Types, etc.
