Previously, we left out the dependency of the QSTR header on
`modules.h`.  This was done to prevent rebuilds of the entire
MicroPython sources whenever a Pycardium module is changed. This
leads to issues where QSTRs got out of sync and weird errors like
the following could happen:

    import foo_module

    Exception: No module `abc_def` (a different string than expected)

Attempt to fix this by only updating the QSTR header when the
module-header actually changes.  For this, a few workarounds are needed:

- Replace symlinks with actual copied files so timestamps change on
  updates.
- Add a hack so meson picks up on the dependency of the file in genhdr/
- Rename the outer file so older meson versions don't complain about
  multiple targets with the same name.

When MXC_ASSERT is disabled, the portexpander_config() call is not
compiled into the bootloader which leads to the portexpander not being
setup correctly and thus neither the screen turns on nor does the button
to switch into MSC mode work correctly (bootloader always goes into MSC
mode).

Fix this by moving the portexpander_config() call outside the MXC_ASSERT
and only keep the return value check inside.  Additionally fix the
pull-up/pull-down selection in portexpander_config() not being set
correctly.

It only has 27 characters, which as far as I can tell are useless for
actual chinese text.

Copying the list of characters in the same order of font24CN.c into
google trans gives out this almost meaningful message:

Lines have been one pixel too short.

I have no idea whether this is something the compiler wouldn't
automatically do, but it can't hurt to be explicit.

RTC_Init will turn off the RTC and readout will not be possible until
RTC_EnableRTCE is called.  The previous version worked because the
bootloader would call RTC_Init and Epicardium would then call
RTC_EnableRTCE.

This broke with the hardware-init changes in

    b76ac8fc

and lead to behavior where cold boot would not enable the RTC.  This
commit switches the order of the two calls in the bootloader so it is
always initialized correctly.  Because some older bootloaders are
already out in the field, this commit also introduces basic rtc init
into Epicardium so the new firmware can work correctly with older
bootloaders.

The bootloader will have initialized the display in all cases so we
don't need to repeat the same init code all over again.
