8358772: Template-Framework Library: Primitive Types

[rm-gh-8]

Backporting JDK-8358772: Template-Framework Library: Primitive Types.

This adds primitive type support to the compiler test template framework library, enabling type-aware code generation for Java primitive types. It is a foundation for additional random expression generation work.

For parity with Oracle JDK.

It is part of a series of dependent PRs for JDK 25, related to the following list of ordered issues:

8358772: Template-Framework Library: Primitive Types
8358600: Template-Framework Library: Template for TestFramework test class
8359412: Template-Framework Library: Operations and Expressions
8367531: Template Framework: use scopes and tokens instead of misbehaving immediate-return-queries
8370489: Some compiler tests miss the @key randomness

Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:

make test TEST=test/hotspot/jtreg/testlibrary_tests/template_framework
make test TEST=test/hotspot/jtreg/compiler
