[lworld] RFR: 8250664: [lworld] Rename 'value type' to 'inline type'

[Tobias Hartmann]

Renamed all inline type specific occurrences of "value" to "inline" in JIT code and tests.

I did not rename:
- Variable names "vt" (for value type) and "vk" (for value klass) because alternative naming "it" and "ik" is already
  used for iterators and instance klasses.
- "MyValue" inline class names in the tests because these are user defined "values".
