Previously, when seeing a `include foo/$(VAR)/bar.mk`, the include
tops wouldn't apply to filter down the results any further.
Allowing include_tops is useful here to prevent cycles in the
load graph.

In make, the result of $(foreach $(x),$(y),$(foreach $(z),(w),a))
is a regular list, but in Starlark it's a list of lists. Flatten
the results of foreach expressions where each element is a list
so that they're regular lists of strings again.

Since the rbc results file is sorted, .KATI_READONLY
ends up trying to make a variable that hasn't been defined
yet readonly, which is an error.
It's not really worth supporting moving it down in the list,
because it wouldn't affect the variable being writable while
still in Starlark code.

Some functions are called without the use of $(call),
since $(call) is not necessary when the function doesn't
take any arguments. mk2rbc thinks these function calls
are local variables, and converts them as such. This
leads to undefined variable errors when trying to load
(before even executing) the starlark file.
Hardcode a known function that should not be converted
to a local variable.

These private variables sometimes have references to make
variables like $< or $@. When converted to starlark, they
become invalid local variables like _< and _@, preventing
the file from being loaded even if it's never executed.

While supporting $(eval) in the general case is
impossible, as it would require emitting code at
runtime, it is possible to handle some special cases
that are common throughout the code base.
Specifically, an assignement expression (where the
left hand side is constant) can be converted without
needing to evaluate strings as code, as its whole
right hand side is treated as one string.
However, this eval with an assignemnt can only be
used as a statement, not an expression. So it requires
the eval to be either a top-level expression, or nested
within other expressions that can be converted to
statements such as $(foreach) or $(if).

This is so that we can set LOCAL_PATH to the result
of my-dir, as LOCAL_PATH can only be set to a string
literal of the exact value of LOCAL_PATH.
It's probably also the correct choice to start phasing

Type hints have the format #RBC# type_hint MY_VAR list
and must be specified at the top of the Makefile. Setting
one will cause that variable to have that type for the
remainder of the Makefile. This can be used where mk2rbc's
type inference detects the wrong type and it must be
manually changed.

- Remove asgnMaybeAppend, it was only used to indicate
that the asignment needs a setDefault. But really, all
types of variable assignments need setDefault if they're
self-referential.
- Remove local_append/local_set_default because there was
no implementation for them written in product_config.rbc
anyways.
- Correct productConfigVariable.emitDefined using the global
variables instead of the product config variables.
- Emit setDefaults for all types of assignments if they're
self referential.

In aosp/1962181 an "optimization" was added where if an include
path with a variable only matches one file, that file would be
called directly instead of going through the whole _entry
variable.
This doesn't work when there is an inherit-product-if-exists call
that matches one file, but that file isn't the one that is specified
at runtime. In reality, the inherit-product-if-exists call should
see that the file doesn't exist and not include anything.
