Bluetooth: audio: Fix call control client build

error: 'CONFIG_BT_TBS_MAX_PROVIDER_NAME_LENGTH' undeclared (first use
			in this function); did you mean
			'CONFIG_BT_TBS_CLIENT_MAX_PROVIDER_NAME_LENGTH'?
  292 |            CONFIG_BT_TBS_MAX_PROVIDER_NAME_LENGTH);
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
      |            CONFIG_BT_TBS_CLIENT_MAX_PROVIDER_NAME_LENGTH
etc.

This fixes build errors that were seen while building call control
client without server side (`CONFIG_BT_TBS`) enabled.
The options like BT_TBS_CLIENT_MAX_URI_LENGTH and
BT_TBS_CLIENT_MAX_PROVIDER_NAME_LENGTH have been removed because those
were not used in the code. In fact the client implementation used the
common options for BT_TBS_MAX_URI_LENGTH and
BT_TBS_MAX_PROVIDER_NAME_LENGTH that were moved in this patch to the
common Kconfig section.
