For code clarity, this commit adjusts the use of `return` statements
in functions with a void return type as follows:
- Transform `return foo();` into separate statements:
`foo();`
`return;`
- Remove unnecessary `return` statements when
they don't affect control flow.

Implement LL_ASSERT_INFO1 and LL_ASSERT_INFO2 for triggering assertions
with parameter information provided for vendor core dump.
Adds Kconfig CONFIG_BT_CTLR_ASSERT_VENDOR by which the new LL asserts
map to BT_ASSERT_VND macros, which shall be implemented in the
debug_vendor_hal.h of the platform. If not enabled, LL_ASSERT_INFO will
map to existing BT_ASSERT_MSG with parameters printed.
Add use of LL_ASSERT_INFO2 where ull_ticker_stop_with_mark() result may
assert.

Generic node_rx_hdr struct contains data not used for done event, so this
pdu specific data is moved to node_rx_pdu to minimize memory usage for
MFIFO_done alloc.
This however calls for a considerable write-through replacing the generic

In order to have clean, self-contained HCI headers that do not have any
dependencies towards the Host or any other part of the system (except
types), reorganize the headers in the following way:
- Split out the macros and structs from hci.h to a new hci_types.h
- Merge the existing hci_err.h into the new hci_types.h

- `/BT_INFO/LOG_INF/`
