[builtins] Introduce a proper BUILTIN frame type.

This adds a new BUILTIN frame type, which supports variable number of
arguments for builtins implemented in hand-written native code (we will
extend this mechanism to TurboFan builtins at some point). Convert the
Math.max and Math.min builtins to construct a BUILTIN frame if required.

This does not yet work for C++ builtins, but that'll be the next step.

This is based off Benedikt's CL at https://codereview.chromium.org/1902373002/.
Fixed a problem with stack drop logic on arm* and mips* and removed an unused
function from the test.

LGTM, thanks.
