  Log Message:
  -----------
  [clang][Interp] Implement dynamic memory allocation handling (#70306)

Implement handling for new/delete/new[]/delete[] expressions via a new
`DynamicAllocator` class.

This introduces four new opcodes:
 - `Alloc` - Allocates one element (`new int(14)`)
- `AllocN` - Allocates N elements of the given primitive (`new
int[100]`)
- `AllocCN` - Allocates N elements of the given (composite) descriptor
(`new S[100]`)
 - `Free` - de-allocates memory allocates using any of the above.
