Bluetooth: TMAP: Add role validation for bt_tmap_register

[Thalley]

Add validation that the device supports the role
set by bt_tmap_register.

fixes #60495

[kruithofa]

Suggested change

	LOG_DBG("Device does not support the CY role");
	LOG_DBG("Device does not support the CT role");

[kruithofa]

This is not specific for this PR, but also shows up other places where CHECKIF is used, and will be compiler dependent:
If the KCONFIG option NO_RUNTIME_CHECKS is set to 'y' a compiler may emit the following warning: static bool valid_tmap_role defined but not used

suggestions for fixing this?

[Thalley]

Two ways we can apply is to guard this call with an IS_ENABLED, or instead of having CHECKIF in the call, we can change all the checks in the functions to use CHECKIF to that if NO_RUNTIME_CHECKS then the function is just a no-op.

But you have a good point that we should do that here

[Thalley]

Looking at the macro it is defined as

#elif defined(CONFIG_NO_RUNTIME_CHECKS)
#define CHECKIF(...) \
	if (0)
#else

With if (0) the code is still compiled, but not linked, and should thus not have any issues. Will leave as is

[kruithofa]

Yes, the code compiles and works fine as is, the only issue is that we get a compiler warning, that shouldn't be there.

would be nice to wrap this very long line?
