llvm-symbolizer: Add a FRAME command.

This command prints a description of the referenced function's stack frame.
For each formal parameter and local variable, the tool prints:

- function name
- variable name
- file/line of declaration
- FP-relative variable location (if available)
- size in bytes
- HWASAN tag offset

This information will be used by the HWASAN runtime to identify local
variables in UAR reports.
