Add GUI option to cover wperf CLI `--sample-display-long` flag

[PrzemekWirkus]

Description

The wperf has command line option --sample-display-long that is related to all sampling functionalities. This flag should be only used in sampling (not counting)

See flag name and description.

    --sample-display-long
        Display decorated symbol name

This flag will de-mangle sampling symbols from:

x_mul:python312_d.dll

to:

static struct _longobject * x_mul(struct _longobject *, struct _longobject *):python312_d.dll

Definition of done

• add new flag as checkbox widget to the extension.
• make sure new de-mangled names (C style) can reside correctly in all widgets.
  • what's new in the symbol name is that there are new special chars like like "_*,()"

How it works

Without the flag:

>wperf record -e ld_spec:100000 -c 1 --timeout 30 -- cpython\PCbuild\arm64\python_d.exe -c 10**10**100
base address of 'cpython\PCbuild\arm64\python_d.exe': 0x7ff765fe1288, runtime delta: 0x7ff625fe0000
sampling .....e..e..e done!
