Fix the alias feature to always prefer the longest match (#2963)

It's possible to configure conflicting aliases such as --alias:a=b and --alias:a/c=d, which is ambiguous for the import path a/c/x (since it could map to either b/c/x or d/x). Previously esbuild would pick the first matching alias, which would non-deterministically pick between one of the possible matches. This release fixes esbuild to always deterministically pick the longest possible match.

Minify calls to some global primitive constructors (#2962)

With this release, esbuild's minifier now replaces calls to Boolean/Number/String/BigInt with equivalent shorter code when relevant:

// Original code
console.log(
  Boolean(a ? (b | c) !== 0 : (c & d) !== 0),
  Number(e ? '1' : '2'),
  String(e ? '1' : '2'),
  BigInt(e ? 1n : 2n),
)

// Old output (with --minify)
console.log(Boolean(a?(b|c)!==0:(c&d)!==0),Number(e?"1":"2"),String(e?"1":"2"),BigInt(e?1n:2n));

// New output (with --minify)
console.log(!!(a?b|c:c&d),+(e?"1":"2"),e?"1":"2",e?1n:2n);

Adjust some feature compatibility tables for node (#2940)

This release makes the following adjustments to esbuild's internal feature compatibility tables for node, which tell esbuild which versions of node are known to support all aspects of that feature:

• class-private-brand-checks: node v16.9+ => node v16.4+ (a decrease)
• hashbang: node v12.0+ => node v12.5+ (an increase)
• optional-chain: node v16.9+ => node v16.1+ (a decrease)
• template-literal: node v4+ => node v10+ (an increase)

Each of these adjustments was identified by comparing against data from the node-compat-table package and was manually verified using old node executables downloaded from https://nodejs.org/download/release/.
