Add an `InputStreamSourceToByteArrayConverter` that can be used to
convert from an `InputStreamSource` (such as a `Resource`) to a
byte array.

This commit restricts how wildcards can be used in search
locations for property files. If a search location contains
a pattern, there must be only one '*' and the location should
end with a '*/'. For search locations that specify the file
name, the pattern should end with '*/<filename>'.

The list of files read from wildcard locations are now sorted
alphabetically according to the absolute path of the file.

Prior to this commit, there was a property server.error.include-details
that allowed configuration of the message and errors attributes in a
server error response.

This commit separates the control of the message and errors attributes
into two separate properties named server.error.include-message and
server.error.include-binding-errors. When the message attribute is
excluded from a servlet response, the value is changed from a
hard-coded text value to an empty value.

  Add support for customizing Spring Session's cookie serializer

Closes gh-20961

See gh-20961

This commit introduces a CookieSerializerCustomizer callback that
allows the customization of the auto-configured
DefaultCookieSerializer bean. This is particularly useful for
configuring cookie serializer's capabilities, such as SameSite, that
are not supported by the Servlet API and therefore not exposed via
server.servlet.session.cookie.* properties.

This commit changes the default builder image from
`cloudfoundry/cnb:bionic-platform-api-0.2` to
`gcr.io/paketo-buildpacks/builder:base-platform-api-0.3`. It also
uses a `paketo-buildpacks/builder` image instead of a
`cloudfoundry/cnb` image to test compatibility with lifecycle v2
and uses paketo naming instead of cloudfoundry when mocking builder
interactions.

Some adjustments to lifecycle phases were also made to align more
closely with the pack CLI.

As a follow-up for gh-21214, this commit renames the property to:

`"server.servlet.register-default-servlet=false"`

Closes gh-21214

This commit adds a new configuration property for configuring the
registration of the default Servlet in Servlet containers.

`"server.servlet.default-servlet.registered=false"`

The default of this property is still `true`, as it's been the case in
previous releases.
