a0c19deb80 LibJS: Implement RegExpCreate/RegExpInitialize closer to the spec 
RegExpInitialize specifies how the pattern string should be created
before passing it to [[RegExpMatcher]]. Rather than passing it as-is,
the string should be converted to code points and back to a "List" (if
the Unicode flag is present), or as a "List" of UTF-16 code units.
Further. the spec requires that we keep both the original pattern string
and this parsed string in the RegExp object.

The caveat is that the LibRegex parser further requires any multi-byte
code units to be escaped (as "\unnnn"). Otherwise, the code unit is
recognized as individual UTF-8 bytes.

345ef6abba LibRegex: Support ECMA-262 Unicode escapes of the form "\u{code_point}" 
When the Unicode flag is set, regular expressions may escape code points
by surrounding the hexadecimal code point with curly braces, e.g. \u{41}
is the character "A".

When the Unicode flag is not set, this should be considered a repetition
symbol - \u{41} is the character "u" repeated 41 times. This is left as
a TODO for now.

0e6375558d AK+LibRegex: Partially implement case insensitive UTF-16 comparison 
This will work for ASCII code points. Unicode case folding will be
needed for non-ASCII.

47f6bb38a1 LibRegex: Support UTF-16 RegexStringView and improve Unicode matching 
When the Unicode option is not set, regular expressions should match
based on code units; when it is set, they should match based on code
points. To do so, the regex parser must combine surrogate pairs when
the Unicode option is set. Further, RegexStringView needs to know if
the flag is set in order to return code point vs. code unit based
string lengths and substrings.

2e45e52993 AK: Add UTF-16 helper methods required for use within LibRegex 
To be used as a RegexStringView variant, Utf16View must provide a couple
more helper methods. It must also not default its assignment operators,
because that implicitly deletes move/copy constructors.

could be promoted to AK::String by the compiler to execute the
comparison.

e4b86aa5d8 Kernel: Fix bug where we half apply pledges in sys$pledge(..) 
This bug manifests it self when the caller to sys$pledge() passes valid
promises, but invalid execpromises. The code would apply the promises
and then return an error for the execpromises. This leaves the user in
a confusing state, as the promises were silently applied, but we return
an error suggesting the operation has failed.

Avoid this situation by tweaking the implementation to only apply the
promises / execpromises after all validation has occurred.

c8b2199251 LibRegex: Clear previous capture group contents in ECMA262 mode 
ECMA262 requires that the capture groups only contain the values from
the last iteration, e.g. `((c)(a)?(b))` should _not_ contain 'a' in the
second capture group when matching "cabcb".
