This CL removes the built-in reference type in favor of a Torque-implemented generic struct, i.e., internal::Reference<T>. It also adds various infrastructure for getting and creating new generic struct instances, as well as matching against them.

For every @noVerifier in base.tq, this change either removes it or
ensures that it has some annotation explaining why it can't be removed.
The @noVerifier usages that can't be removed fall into the following
categories:
1. Classes that don't have their own instance types and therefore have
no meaningful way to do an Is...() check
2. Fields that might not exist
3. Fields that are waiting for MaybeObject support in Torque

This CL adds lint errors for unused Torque macros. To prevent lots of
noisy warnings, the check is rather narrow. Macros declared as "extern"
or marked with "@export" are ignored. Also macros starting with "Convert",
"Cast" or "FromConstexpr" are not checked.
Drive-by: Removing some unused macros.

This CL adds a lint error for variables that are unnecessarily bound
with 'let' when they could be bound using 'const. This test is skipped
for struct types. For struct types, the "constness" also depends on
the struct methods called and whether these methods write to the struct
or not. This is not straight-forward to detect.
Drive-by: Fix all the newly introduced lint errors.

This CL introduces an 'import' statement. It does not produce any AST
node. The AST contextual directly collects what source id imports what other
source id.
Currently the import map is unused. In the future, import syntax will be
used to implement partial compilation.

This CL adds lint errors when 'let' bindings, arguments and labels
are not used. Note that errors for 'const' bindings will be added
later.
In cases where arguments are actually needed to match the signature,
the warning can be silenced by prefixing identifiers with "_". This
might be needed for generic specializations or builtins called from
TurboFan. Trying to use a variable or label that was marked with
"_" results in a compilation error.
Implicit arguments are not linted. They are implemented using exact
string matching. Prefixing an implicit argument with "_" in a callee
would break all callers as the names would no longer match.
Drive-by: Fix all new lint errors in the existing Torque code.

This CL changes the existing TorqueError struct into a more general
TorqueMessage by adding a "kind" enum. The contextual for lint errors
is removed and replaced by a list of TorqueMessages.
A MessageBuilder is introduced to help with the different
combinations of present information and method of reporting. A lint
error with custom SourcePosition can be reported like this:
Lint("naming convention error").Position(<src_pos_var>);
While a fatal error, with CurrentSourcePosition can be thrown
like this:
Error("something went horrible wrong").Throw();
This approach is both backwards compatible and should prove flexible
enough to add more information to messages or add other message kinds.

This CL changes lint errors to not be printed directly to stderr.
Instead, they are collected in a list that gets surfaced via
the TorqueCompilerResult. This is done so they can be presented
to language server clients.
This change also removes the "abort_on_lint_errors" option.
API users can now decide for themselves what to do, depending on
the presence of lint errors in the returned list.

if the number of moved elements is bigger than the number of deleted
