drivers: i2c_nrfx_twim: Fix write transaction issues

drivers: i2c_nrfx_twim: Use concatenation buffer by default

Issue an error logging message when the i2c_nrfx_twim driver lacks
a concatenation buffer big enough to properly handle a call to
i2c_burst_write() function, to give the user a hint what is wrong.

Also use by default a 16-bytes long concatenation buffer for every
instance of the i2c_nrfx_twim driver. Such value should cover most
of the simple uses of the i2c_burst_write() function, like those
in the stmemsc sensor drivers, and when a longer buffer is needed,
the user will be provided with the above message pointing to the
property that should be adjusted.

Fixes #33440.

drivers: i2c_nrfx_twim: Add handling of buffers located in flash

TWIM peripherals cannot perform write transactions from buffers
located in flash. The content of such buffers needs to be copied
to RAM before the actual transfer can be requested.
This commits adds a new property (zephyr,flash-buf-max-size) that
informs the driver how much space in RAM needs to be reserved for
such copying and adds proper handling of buffers located in flash.
This fixes an issue that caused that e.g. the DPS310 sensor driver
did not work on nRF SoCs that only have TWIM, not TWI peripherals.

Fixes #35550.

Rebased.

[00:00:16.188,903] <err> i2c_nrfx_twim: Need to use concatenation buffer and provided size is 
insufficient (1 + 1024 > 16). Adjust the zephyr,concat-buf-size property in the "I2C_0" node.

I would make it shorter.

Well, I wanted to give the user a clear indication what is wrong and how to solve the problem. Hence such verbose message. But the message is not supposed to occur normally, as it indicates an invalid build configuration, so I think its length should not be a problem and I'd rather keep it as it is.
