Add shader pointer parameter tests, including for `unrestricted_point…

…er_parameter` support (gpuweb#3265)

* Rename `requireLanguageFeatureOrSkipTestCase`

To `skipIfLanguageFeatureSupported` to match all the other skip methods.

* [shader] Add pointer parameter execution tests

Checks reading and writing to pointer parameters, with and without the 'unrestricted_pointer_parameters' WGSL feature

* [shader] Update function validation tests for UPP

Update the `webgpu:shader,validation,functions,restrictions` tests to handle the `unrestricted_pointer_parameters` WGSL feature
