"static const" instead of "#define" for script API M_* constants.

This makes referenced script API M_* constants visible in the debugger.

Modify rs lldb test for the constants so that it references them.

Adapted from https://android-review.googlesource.com/#/c/210789/

Test: aosp_arm64-eng on emulator
- run slang/tests, slang/lit-tests
- run rs lldb test suite
- run RsTest (32-bit, 64-bit)
- run cts -m RenderscriptTest (32-bit)
- confirmed that omitting type: or value: from constant: causes
  script_api/generate.sh to fail with an error
