Add global suppress_platform_verbose parameter (#10319)

## Summary

Adds a global configuration parameter **`suppress_platform_verbose`**
(bool, default `false`).

When set to `true`, memory and time information is suppressed from
verbose output — the same behavior as the `-V` flag proposed in #10301,
but driven by a global parameter instead of a dedicated command-line
switch. This yields deterministic, platform-independent verbose output
that is useful for testing and diffing.

Usage:
```
z3 -v:2 suppress_platform_verbose=true problem.smt2
```

## Approach

Instead of introducing a `-V` command-line flag (#10301), this registers
`suppress_platform_verbose` as a global parameter via `env_params`,
wired to a lightweight `get_suppress_platform_verbose()` flag in `util`.

Verbose output sites guard only their **memory** (`mem_stat`) and
**time** (`m_watch` / `:time` / `:before-memory` / `:after-memory`)
fields on this flag. Platform-independent counters (e.g. `:cost`,
`:threshold`, `:elim-vars`) are always emitted.

Affected sites:
- SAT: asymm-branch, probing, scc, simplifier (subsumer /
blocked-clauses / resolution), solver stats (`sat.stats`, `:memory`,
`mk_stat`)
- SMT: context stats (`smt.stats`)
- Tactic report (`:time`, `:before-memory`, `:after-memory`)

## Validation

- Release build succeeds.
- `suppress_platform_verbose` appears in `z3 -pd` with the correct
type/default, and is accepted on the command line.
- All 93 `test-z3 /a` unit tests pass.

Closes the need for the `-V` switch in #10301.
