This commit reworks the setup procedure for the OpenAMP trace buffer,
used by the libmetal framework to provide cross-core logging data if
needed.
Before these changes, the buffer was provided by MicroPython, as a fixed
size 128 bytes chunk that was accidentally put into the .rodata section,
making it not usable for its intended purpose.
Now, a buffer placed in .bss with a default size of 128 bytes is
provided by MicroPython unless chosen otherwise. A user-chosen buffer
pointer can be provided to MicroPython using the
MICROPY_PY_OPENAMP_TRACE_BUF preprocessor definition. If what
MicroPython provides by default is fine, the buffer size can be
overridden with a new value for the MICROPY_PY_OPENAMP_TRACE_BUF_LEN
preprocessor definition instead.

Use new function mp_obj_new_str_from_cstr() where appropriate. It
simplifies the code, and makes it smaller too.

Use the existing metal log handling mechanism instead of overriding the
metal_log, which causes build issues when logging is enabled.

RemoteProc provides an API to load firmware and control remote processors.
Note: port-specific operations must be implemented to support this class.

This module implements OpenAMP's basic initialization and shared resources
support, and provides support for OpenAMP's RPMsg component, by providing
an `endpoint` type (a logical connection on top of RPMsg channel) which can
be used to communicate with the remote core.
