According to the Javadoc for ServletRequest's getServerName() method,
when the `Host` header is set, the server name is "the value of the
part before ':' in the Host header value ...". For a value representing
an IPV6 address such as `[::ffff:abcd:abcd]`, the enclosing square
brackets should therefore not be stripped from the enclosed IPV6
address.
However, the changes made in conjunction with gh-16704 introduced a
regression in Spring Framework 4.1 for the getServerName() method in
MockHttpServletRequest by stripping the enclosing brackets from the
IPV6 address in the `Host` header. Similarly, the changes made in
conjunction with gh-20686 introduced a regression in Spring Framework
4.3.13 and 5.0.2 in the getRequestURL() method in
MockHttpServletRequest by delegating to the getServerName() method
which strips the enclosing brackets.
This commit fixes the implementation of getServerName() so that the
enclosing brackets are no longer stripped from an IPV6 address in the
`Host` header. The implementation of getRequestURL() is therefore also
fixed.
In addition, in order to avoid a NullPointerException, the
implementations of getServerName() and getServerPort() now assert that
an IPV6 address present in the `Host` header correctly contains an
opening and closing bracket and throw an IllegalStateException if that
is not the case.

This commit disables warnings for annotation processing in spring-test
in order to get the build passing again after it mysteriously started
failing in 2020.
Prior to this commit, the schemaZip Gradle task failed to find Spring
schema files on MS Windows due to path separators hard coded to forward
slashes that are not compatible with the Windows operating system.
Consequently, a full build failed on Windows since the distZip task was
not able to locate the zipped schema archive that the schemaZip task
failed to create.
This commit fixes this by updating the schemaZip task to search for
schema files using backslashes as well as forward slashes.
Closes gh-23933
