Replace `zassert` with `zassert_equal` in CRC8-CCITT and CRC8-ROHC
test cases, as `zassert_equal` is more appropriate for comparing
actual and expected values.

This commit introduces the `crc8_rohc` function to the CRC library,
implementing the CRC-8/ROHC (RObust Header Compression) variant.
This algorithm is widely used in networking protocols, which is commonly
found in modem subsystems.

Add a bunch of missing "zephyr/" prefixes to #include statements in
various test and test framework files.

In order to bring consistency in-tree, migrate all tests to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

As described in #42403, there was an issue with the existing crc16_ansi()
implementation, since it was not calculating the CRC-16-ANSI (aka
CRC-16-MODBUS). This is because the existing crc16() function only
supported non-reflected input and output (and the CRC-16-ANSI requires
reflection on both) and also it did not seem to support correctly inial
seeds different from 0x0000 (and, again, the CRC-16-ANSI requires 0xffff
as an initial seed).
This commit replaces the existing crc16() with a functional pair,
crc16() and crc16_reflect(), that also work with any poly, any initial seed
and allow to select whether reflection is performed.
It also adapts crc16_ansi() so that it actually returns the correct CRC.
Fixes#42403.

Since the crc16_ccitt and crc16_itu_t functions can compute several
flavors of checksum depending on the initial seed and XOR out value, add
tests for some common variants that are documented as supported.
