* [tests] Duplicate Microsoft.Diagnostics.NETCore.Client dependent tests for Linux arm

* Fix debuginfo/tester test skip

* Temporarily enable bigevent on Linux arm and remove duplicate exclude

* Fix unaligned UTF16 string read in collect tracing EventPipe command.

Collect tracing 2 EventPipe command triggers an unaligned UTF16 string
read that could cause a SIGBUS on platforms not supporting unalinged
reads of UTF16 strings (so far only seen on 32-bit ARM Linux CI machine).

On CoreCLR this could even cause a unalinged int read due to
optimizations used in UTF8Encoding::GetByteCount.
