[Bug #20050]

	[Bug #20327] Do not count subsecond to calculate UTC offset

	Assume that there will never be any time zones with UTC offsets that
	are subseconds.  Historically, UTC offset has only been used down to
	the second.

	Fix crash when checking symbol encoding

	[Bug #20245]

	We sometimes pass in a fake string to sym_check_asciionly. This can crash
	if sym_check_asciionly raises because it creates a CFP with the fake
	string as the receiver which will crash if GC tries to mark the CFP.

	For example, the following script crashes:

	    GC.stress = true
	    Object.const_defined?("\xC3")

	Fix coderange of invalid_encoding_string.<<(ord)

	Appending valid encoding character can change coderange from invalid to valid.
	Example: "\x95".force_encoding('sjis')<<0x5C will be a valid string "\x{955C}"

	Memory leak with TracePoint on bmethod

	[Bug #20194]

	When disabling the TracePoint on bmethod, the hooks list is not freed.

	For example:

	    obj = Object.new
	    obj.define_singleton_method(:foo) {}
	    bmethod = obj.method(:foo)
	    tp = TracePoint.new(:return) {}

	    10.times do
	      100_000.times do
	        tp.enable(target: bmethod) {}
	      end

	      puts `ps -o rss= -p #{$$}`
	    end

Skip the test_interrupt_in_other_thread test failing on Travis arm32.
The failing test is not a new issue. It had already been skipped in .travis.yml
before updating .travis.yml.
https://github.com/ruby/ruby/blob/7b05cb8dbbd637910757f402e64da3908b4bb809/.travis.yml#L99-L101

Note that RUBY_PLATFORM is "armv8l-linux-eabihf" on Travis arm32 pipeline.
And the readline was deleted in both master and ruby_3_3 branches.
https://github.com/ruby/ruby/commit/59fd67fc3d405e529e038172e769ff20a8fb5535

So, we only need this commit on ruby_3_2 and older Ruby version branches.
