  [CSSPGO]Add a flag to limit unsymbolized context depth (#121531)

Adding a new flag(`--csprof-max-unsymbolized-context-depth`) to only
limit unsymbolized context depth. Currently,`--csprof-max-context-depth`
applies to both symbolized and unsymbolized profile context, there are
scenarios where `--csprof-max-context-depth` may not be flexible enough,
e.g. if we want to limit the context but still keep all the inlinings
from the leaf frame, we could set the value
csprof-max-unsymbolized-context-depth >= 1.
