Reduces our memory consumption/allocations for VMLA executables by quite a bit.

This replaces WTF with Tracy, which can be enabled in cmake builds with
IREE_ENABLE_RUNTIME_TRACING. Bazel support will come soonish. This initial commit provides a full C API for Tracy, C++ shims for the existingIREE_TRACE_SCOPE0macro (what's mostly used in the codebase today), and allocation tracking.This has the side effect of removing another ALWAYSLINK library. Yay!
Progress on #1886; C API is in but still need to finish the C++ API before calling this done. Vulkan tracing will be added separately with #1937 as that requires more work.
Fixes #1480.
