robert-hh 5c78762c16 mimxrt/machine_i2c_target: Support I2C target mode. ...

The functionality is similar to the RP2 implementation.  The supported
address size is 7 bit.  In order to achieve a sufficient response, the
target I2C IRQ handler has to run from RAM, causing much more code moved to
RAM than required.

Tested with Teensy 4.1, MIMXRT1021EVK, MIMXRT1011EVK and MIMXRT1170, using
both a On-Board SoftI2C as controller and a RP2 Pico as external
controller.
