In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

Replace the custom float32_value_t LwM2M type with native double, to
facilitate LwM2M API and improve floating point precission.

Floating point parser for plain text format was parsing floats wrongly,
ignoring leading zeros after decimal points.
Fix this, by reusing atof32() function, already avaialbe in a different
part of the engine, which did the parsing correctly.

According to the specificaion, resources are not predefined to use 32 or
64 bit floating point numbers, but should rather accept any of them (as
indicated by the size of the TLV in the message). This lead to issues
for instance with Eclipse Leshan LWM2M server, where Leshan sent 64-bit
value, while Zephyr expected 32-bit, making it impossible to write
the resource.
Therefore, unify the float usage to 32-bit float representation and fix
the TLV parsing functions, to accept values sent as either 32 or 64 bit
float.

During the initial work on LwM2M, the float32/64 code was
basically stubbed out. Float32 sent only whole values and
float64 was completely broken.
Let's clean up the OMA TLV formatting code by moving the float
processing code into a separate file: lwm2m_util.c.
Then using public definitions for binary32 and binary64, let's
fix the processing code to correctly fill the float32_value_t
and float64_value_t types.
