This commit updates the whole Spring Framework codebase to use JSpecify
annotations instead of Spring null-safety annotations with JSR 305
semantics.
JSpecify provides signficant enhancements such as properly defined
specifications, a canonical dependency with no split-package issue,
better tooling, better Kotlin integration and the capability to specify
generic type, array and varargs element null-safety. Generic type
null-safety is not defined by this commit yet and will be specified
later.
A key difference is that Spring null-safety annotations, following
JSR 305 semantics, apply to fields, parameters and return values,
while JSpecify annotations apply to type usages. That's why this
commit moves nullability annotations closer to the type for fields
and return values.

Prior to this commit, the `DatabaseClient` interface would allow batch
operations for binding parameters by their names and values. Positional
parameters did not have such equivalent.
This commit adds a new `bindValues(List<?>)` method variant for adding
multiple positional arguments in a single call and avoiding allocation
overhead when the parameters count is large.

NamedParameterUtils in spring-r2dbc now supports MySQL-style backticks

This commit replaces uses of onErrorResume() with
- onErrorMap() in places where onErrorResume() is just used to map to a
different exception.
- onErrorComplete() where onErrorResume() just maps to Mono.empty().
- onErrorReturn() where onErrorResum() just maps to Mono.just().

This commit introduces initialize() methods in
AbstractRoutingDataSource and AbstractRoutingConnectionFactory as an
alternative to invoking afterPropertiesSet().

This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
