Add --move-to-nearest-code / target.move-to-nearest-code options

Summary:
This option forces to only set a source line breakpoint when there is an exact-match

This patch includes the following commits:
# Add the -m/--exact-match option in "breakpoint set" command
## Add exact_match arg in BreakpointResolverFileLine ctor
## Add m_exact_match field in BreakpointResolverFileLine
## Add exact_match arg in BreakpointResolverFileRegex ctor
## Add m_exact_match field in BreakpointResolverFileRegex
## Add exact_match arg in Target::CreateSourceRegexBreakpoint
## Add exact_match arg in Target::CreateBreakpoint
## Add -m/--exact-match option in "breakpoint set" command
# Add target.exact-match option to skip BP if source line doesn't match
## Add target.exact-match global option
## Add Target::GetExactMatch
## Refactor Target::CreateSourceRegexBreakpoint to accept LazyBool exact_match (was bool)
## Refactor Target::CreateBreakpoint to accept LazyBool exact_match (was bool)
# Add target.exact-match test in SettingsCommandTestCase
# Add BreakpointOptionsTestCase tests to test --skip-prologue/--exact-match options
# Fix a few typos in lldbutil.check_breakpoint_result func
# Rename --exact-match/m_exact_match/exact_match/GetExactMatch to --move-to-nearest-code/m_move_to_nearest_code/move_to_nearest_code/GetMoveToNearestCode
# Add exact_match field in BreakpointResolverFileLine::GetDescription and BreakpointResolverFileRegex::GetDescription, for example:

```

Test Plan:
./dotest.py -v --executable $BUILDDIR/bin/lldb functionalities/breakpoint/
./dotest.py -v --executable $BUILDDIR/bin/lldb settings/
./dotest.py -v --executable $BUILDDIR/bin/lldb tools/lldb-mi/breakpoint/
