Add an XML schema for documentation
This makes it easier to spot syntax errors when editing the
class reference. The schema is referenced locally so validation
can still work offline.

Each class XML's schema conformance is also checked on GitHub Actions.

Integer built-in type.
</brief_description>
<description>
Signed 64-bit integer type.
It can take values in the interval [code][-2^63, 2^63 - 1][/code], i.e. [code][-9223372036854775808, 9223372036854775807][/code]. Exceeding those bounds will wrap around.
[int] is a [Variant] type, and will thus be used when assigning an integer value to a [Variant]. It can also be enforced with the [code]: int[/code] type hint.
[codeblock]
var my_variant = 0 # int, value 0.
my_variant += 4.2 # float, value 4.2.
var my_int: int = 1 # int, value 1.
my_int = 4.2 # int, value 4, the right value is implicitly cast to int.
my_int = int("6.7") # int, value 6, the String is explicitly cast with int.
var max_int = 9223372036854775807
print(max_int) # 9223372036854775807, OK.
max_int += 1
print(max_int) # -9223372036854775808, we overflowed and wrapped around.

<description>
Cast a [bool] value to an integer value, [code]int(true)[/code] will be equals to 1 and [code]int(false)[/code] will be equals to 0.

<return type="int" />

<description>
Cast a float value to an integer value, this method simply removes the number fractions (i.e. rounds [code]from[/code] towards zero), so for example [code]int(2.7)[/code] will be equals to 2, [code]int(0.1)[/code] will be equals to 0 and [code]int(-2.7)[/code] will be equals to -2. This operation is also called truncation.

<return type="int" />
<argument index="0" name="from" type="String" />
<description>
Cast a [String] value to an integer value, this method is an integer parser from a string, so calling this method with an invalid integer string will return 0, a valid string will be something like [code]'1.7'[/code]. This method will ignore all non-number characters, so calling [code]int('1e3')[/code] will return 13.
