RFR: 8327255: javac lint warnings: removal, missing-explicit-ctor

[Kevin Rushforth]

This PR updates `build.gradle` to define javac lint options for three different types of java compilation tasks: sdk classes, test classes (including shims), and tool classes (including JSLC). The defaults for these three groups of lint options are specified in `build.gradle`.

We also define three gradle properties that can be used at build time to override the global lint options for each of the three categories of tasks as follows:

* `LINT` - used when compiling sdk tasks : default = "removal,missing-explicit-ctor"
* `TOOL_LINT` - used when compiling tool tasks : default = ""
* `TEST_LINT` - used when compiling test tasks : default = ""

Each property takes a string with a comma-separated list of lint options. For example:


gradle -PLINT="deprecation,removal" sdk


I provided a build mechanism to add extra per-module lint options in `build.gradle`. None are currently defined, but I tested the logic to show that it can be. I did not provide a way to override the per-module lint options via the command line. Once we start using them, we might consider adding that.

While testing this PR, I ran into a few places where we need to suppress removal warnings for use of our own internal classes that are terminally deprecated, so I filed [JDK-8334143](https://bugs.openjdk.org/browse/JDK-8334143) to track this, and added the missing annotations in this PR.

I also tested with JDK 23 to verify that we are now getting the expected warnings for the use of sun.misc.Unsafe, and filed two bugs --[JDK-8334138](https://bugs.openjdk.org/browse/JDK-8334138) to (temporarily) suppress those warnings in this PR and [JDK-8334137](https://bugs.openjdk.org/browse/JDK-8334137) to eventually fix them by replacing our use of sun.misc.Unsafe.
