This commit introduces the option to place the mbed TLS heap in a custom
memory section. The heap might be quite large depending on concurrent
TLS connections, thus it might be needed to place this manually

This commit just moves some code around. For sake of cleanliness
a new file is added to hold the entropy parsing functions

- Slightly improve the name of this kconfig adding the suffix
_POLL in order to highlight that this adds a callback
function used to poll data.
- Description was also updated to point out that this symbols
might not only use the (secure) entropy driver, but also
generic number generators, some of which are not really
secure.
- The symbol was move from Kconfig to Kconfig.tls-generic because
this is where MBEDTLS_ENTROPY_C is located and since
MBEDTLS_ENTROPY_HARDWARE_ALT depends on the former (it only
makes sense if the entropy module is also enabled), we add
also the "depends on".

In device init phase, it will call _mbedtls_init before malloc_prepare
as mbedtls has higher priority defined in SYS_INIT..
_mbedtls_init() will call psa_crypto_init() and malloc buffer,
but z_malloc_heap is not initialized, which will cause device hang.
Should call malloc_prepare() before _mbedtls_init to fix this issue,
so decrease the priority of mbedtls to default 40.

Mbed TLS acts as a PSA crypto client. This will setup the PSA

rand32.h does not make much sense, since the random subsystem
provides more APIs than just getting a random 32 bits value.

SYS_INIT() requires pointer to function that takes `void` now, instead of
pointer to device structure. Since the commit was developed before that
switch, it still invoked it with NULL. Fix that now.

Add a config flag to enable conditional mbebtls
initialization at startup, defaulting to enabled.
Also add a function, mbedtls_init(), that should be
called by platforms that wish to initialise mbedtls
at a time of their choosing.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

mbedTLS library threshold initialization was done in native TLS socket
implementation (which tends to use mbedTLS now) and inside mbedTLS
benchmark test. Move that to mbedTLS module initialization, as this is a
global setting.

mbedtls_debug_set_threshold() is called.
