[Feature] Package Plugin to use TP Included JRE

[DissonantAU]

Switches for changing the JRE from system to the TP one would be great

Ideally:

• Switches for enabling individually for each OS (Win/Mac/Linux)
  • eg Enable for Windows & Linux, leave default for Mac
• Switch for enable for 'default start'/plugin_start_cmd
• Enabling uses the %TP_JAVA_FILE% value for chosen OS/in default
• Switches should accept providers from Gradle, allowing for use of meta-tasks to enable them for different build jobs
  • e.g. a task could build an 'integrated' tpp with all switches enabled and a default tpp that expects Java 8 JRE installed on the system

I noticed there was some work on something like this in the code around entry.tp generation, but there was no way to enable it

I've created a Branch for this for both v8.3 and v9:
Both are based on the #74 Branches

8.3:
https://github.com/DissonantAU/TouchPortalPluginSDK/tree/dev-8.3-gr7.6-deplib-tpjre
9.0:
https://github.com/DissonantAU/TouchPortalPluginSDK/tree/develop-gr7.6-deplib-tpjre

Annotation Processor Arguments/Options/Switches can be supplied to tell the Plugin whether to use java or %TP_JAVA_FILE% in the enthry.tp start command

I've not updated the example build scripts to show this
