py/parse: Add MICROPY_COMP_CONST_TUPLE option to build const tuples.
This commit adds support to the parser so that tuples which contain only constant elements (bool, int, str, bytes, etc) are immediately converted to a tuple object. This makes it more efficient to use tuples containing constant data because they no longer need to be created at runtime by the bytecode (or native code). Furthermore, with this improvement constant tuples that are part of frozen code are now able to be stored fully in ROM (this will be implemented in later commits). Code size is increased by about 400 bytes on Cortex-M4 platforms. See related issue #722. Signed-off-by: Damien George <damien@micropython.org>pull/8504/head
