Kim-Anh Tran a7c8a3ea9b [debugger] Consider close-by functions when setting a breakpoint
This changes the behavior of SetBreakpointForScript to find more
accurate break positions.

Previously, setting a breakpoint would only consider the shared
function info that contained the requested position for setting a
breakpoint. More intuitively, a breakpoint should not necessarily
be set in a function that contains the position, but in the closest
breakable location that comes after the position we requested.

To achieve this we:
1. find the shared function info of the inner most function
that contains the requested_position.
This function's end position is used to find other shared function
infos in step 2.

2. search for all shared function infos that intersect with the
range [requested_position, inner_most_function.break_position[.

3. From the shared function infos extracted in 2, find the one
that has the closest breakable location to requested_position.

Checks if we can set a breakpoint on a one-line inline functions.
Setting breakpoint on `class X`
function foo() {}
var bar = "bar";
class X {
constructor() {
|_|this.x = 1;
}
[bar] = 2;
baz = foo();
}
new X();
Setting breakpoint on constructor, should resolve to same location
function foo() {}
var bar = "bar";
class X {
constructor() {
|_|this.x = 1;
}
[bar] = 2;
baz = foo();
}
new X();
Setting breakpoint on computed properties in class
function foo() {}
var bar = "bar";
class X {
constructor() {
this.x = 1;
}
[|_|bar] = 2;
baz = foo();
}
new X();
Setting breakpoint on initializer function
function foo() {}
var bar = "bar";
class X {
constructor() {
this.x = 1;
}
[bar] = 2;
baz = |_|foo();
}
new X();
