[LWIP] Correctly synchronize to lwIP 1.4.1 (#6123)

* [TCPIP] Rename lwip library to lwipcore

* [TCPIP] Remove ReactOS-specific code from LWIP library

* [TCPIP] Synchronize LWIP code to 1.4.1

Update to LWIP 1.4.1 should have been done by bd3b0e8ef4
However, I was unable to find the exact revision used in this commit.

So, do the following
- take code from STABLE-1_4_1 commit on https://git.savannah.gnu.org/git/lwip.git
- cherry-pick LWIP 32aa9a41e2013e5ee6eee09317a848647e37badf (CORE-8978)
- cherry-pick LWIP c0b534e5318baf870e2152c70d4d11a3a86181f3
- add a ReactOS-specific change in src/api/tcpip.c (missing include)
- add ReactOS specific file CMakeLists.txt

NOTE: Changes are mostly in unit test files (not used) and CHANGELOG file.

CORE-7140
