Fix logic errors in match-statement Array & Dictionary patterns

[cdemirer]

Fixes #57004
Fixes #57150

This fixes 2 logic errors about match statements.

The first is about the order of logical operations. Currently, ORing with the result of the previous pattern of the same branch happens before checking the elements of the Array / Dictionary (for the respective patterns). This causes weird behavior, ranging from skipped cases (#57004) to runtime errors:

func _ready():
    match 1:
        1, [2]: # Runtime error: Invalid get index '0' (on base: 'int').
            print('A')

The second is specific to the Dictionary Pattern. When the pattern has a key with no value supplied, it is supposed to require the existence of the key in order to successfully match. However, currently its existence only contributes to the result if there is also a value supplied. (#57150)

Looks good. Could you add some test cases for this?

Added test cases.

Thanks! And sorry for the delay.
