Adds SEMA tests to verify correct SVE/SME builtin usage based on the calling function's type (i.e. normal, streaming or streaming compatible). For invalid uses the tests verify the expected diagnostic is emitted. This exposed an issue whereby some builtins are incorrectly callable by streaming compatible functions, which this PR fixes. The tests are autogenerated based on the builtin definitions (e.g. arm_sve.td). This is achieved by extending SVEEmitter, which can now emit a JSON file containing builtin usage information that can be fed to aarch64_builtins_test_generator.py that is also part of this PR.

Adds SEMA tests to verify correct SVE/SME builtin usage based on the calling function's type (i.e. normal, streaming or streaming compatible).
For invalid uses the tests verify the expected diagnostic is emitted. This exposed an issue whereby some builtins are incorrectly callable by streaming compatible functions, which this PR fixes.
The tests are autogenerated based on the builtin definitions (e.g. arm_sve.td). This is achieved by extending SVEEmitter, which can now emit a JSON file containing builtin usage information that can be fed to aarch64_builtins_test_generator.py that is also part of this PR.
