license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2.

shell: Improve handling of log messages If burst of log messages was passed to the shell log backend, it was likely that messages were lost because shell had no means to control arrivals of log messages. Added log message enqueueing timeout to the shell instance to allow blocking logger thread if short-term arrival rate exceeded shell capabilities. Added kconfig option for setting log message queue size and timeout in RTT and UART instances. Added section in shell documentation which explains interaction between the logger and shell instance acting as a logger backend.
