gh-130693: Add options of the tkinter.Text.search method: -nolinestop -all -overlap -strictlimits

[sharktide]

Add options -nolinestop, -all, -overlap, and -strictlimits to the search function of the text class of tkinter.

Fixes #130693
Closes #130693

Tested against

.\PCbuild\amd64\python_d.exe -m test -ugui test_tkinter

And test passed. Result:

0:00:00 [1/1] test_tkinter
0:00:27 load avg: 3.93 [1/1] test_tkinter passed

== Tests result: SUCCESS ==

1 test OK.

Total duration: 27.6 sec
Total tests: run=787 skipped=11
Total test files: run=1/1
Result: SUCCESS

Also tested against a custom test file:

import tkinter as tk

root = tk.Tk()
text = tk.Text(root)
text.pack()

text.insert('1.0', 'This is a test. This is only a test.\nAnother line.\nYet another line.')

# Test without options
result = text.search('test', '1.0', 'end')
print('Without options:', result)

# Test with -nolinestop
result = text.search('line', '1.0', 'end', nolinestop=True, regexp=True)
print('With -nolinestop:', result)

# Test with -all
result = text.search('test', '1.0', 'end', all=True)
print('With -all:', result)

# Test with -overlap
result = text.search('test', '1.0', 'end', overlap=True, all=True)
print('With -overlap:', result)

# Test with -strictlimits
result = text.search('test', '1.0', 'end', strictlimits=True)
print('With -strictlimits:', result)

root.mainloop()

Which returns:

Without options: 1.10
With -nolinestop: 2.8
With -all: (<textindex object: '1.10'>, <textindex object: '1.31'>)
With -overlap: (<textindex object: '1.10'>, <textindex object: '1.31'>)
With -strictlimits: 1.10

Indicating that the new features are functioning correctly

• Issue: tkinter missing -nolinestop on tk.Text #130693

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.
